You are there because that is how Elo-Type Rank-Systems are designed. You now need to potentially win hundreds of matches now to get into Gold-Ranked. This is one of the many reasons why people simply create new/smurf-accounts. It's honestly MUCH FASTER & easier to get into Gold on a Brand-New account than trying to climb up from a Tanked Main-Account.
The REASON for this is in the mathematical-system/formula. This has even been complained about in CHESS-circles for your information. A brand new account is rated at 1200, and if there are nothing BUT other brand-new accounts, you can only get so many maximum points from a win, and MOST accounts are going to be much closer to the 1200-score (a Bronze-rated score by the way).
You simply are not going to get that many points from placements if you are matched against other accounts of 1200-ratings even if you win 10 placements in a row. From what I can remember from the Chess-Article (I don't have a link to it right now but I can attempt to find & add it later if schedule permits), the Elo-System attempted to count for over-all inflation & deflation of points in the over-all system-pool, considering that high-rated players often would simply quit playing or play very rarely in order to protect their scores (thus taking the over-all available total points out of the system-pool).
If you had two people in an Elo-System, even if one of them won 100% of the time, the maximum score they could probably get would likely be 1400 or 1600 maximum (Silver-Gold-Ranked), with the one constantly losing going down to maybe 1000 or 800 points minimum. Over-all, the average score amongst two players in an Elo-Pool should be around 1200, considering that 1400 + 1000 divided by 2 = 1200. Remember, this is the BEGINNING of the Season, when LESS POINTS are available in the system that you can "take" from other players who've elevated their Rank-Score through winning & taking points from others out of the Points-Pool.
Ranking systems like these are a lot like Stock-Markets. For someone to gain points, another is basically required to lose points, somewhat like how a lottery winner's gains are from the losses of everybody having spent their money on tickets but not being the one who won. This also can mathematically explain why there can be so many people rated in the Silver/Bronze-Divisions who have a lot of difficulty getting out (because, rather than making new accounts, they try to press on with their main-accounts, when really they would benefit more economically from making a new account instead).
Another benefit of having multiple accounts is that you can basically queue-dodge against guaranteed losses with near-impunity until you run out of accounts to use for the day. What I mean by this is that, points-farming strategies exist which can be used to help manipulate your ranking towards the higher numbers more quickly, rather than throwing things to the luck/chance of random match-making, and if you ONLY queue-dodge ONCE per day per account, you ONLY lose 3LP (per account), and THAT will go a LONG way into helping you climb FASTER (I queue-dodged over 500x on my account last season, but you would know why if you have multiple days of 20 idiot-teams in a row feeding like a buffet starting from even before lane-phase even started followed by four-man-surrender-voting against you [thus why I changed my account-name to its current one], and I'm NOT joking on this, the fucking trolls caused my W/L ratio to be a mere 11 wins to 48 LOSSES at the beginning of the season, causing DEMOTIONS into BRONZE in the Season TWO TIMES in the SAME damn Season [from dumb-asses being matched into my team for multiple matches in a row], and I DID eventually get to Gold after around 1600 matches played [even though it occurred after Season-Rewards], but like I said, I also queue-dodged over 500x since my W/L-ratio would have been shit if I had not, and my mistake was simply not limiting queue-dodges to only ONCE per day so my LP-losses would often go down 100LP in the same day).
"Why are you in Bronze with your skill-level ?" and "How the HELL did these idiots even manage to get Gold-Ranked" are COMMON statements within my matches. Anyway, stop wasting time on your main-account, just make another one instead. You can even designate specific accounts to be used for specific-roles or you can configure every single account to be exactly the same so that you can just One-Trick-Pony your way & queue-dodge if you don't get to use your one-trick-pony for a queue & then re-try again into another queue with the next account.
