Snowballing or catcing up as an adc

So, i recently disovered an item that allows adcs to snowball or catch up if they reallllly need to. Te item in question is avarice blade. I know you wont believe me but the math is simple only if you get it early on. It acts as a crit item but, it also gives gold. Gold is the only thing you need to win so if you get this item early on its more an worth because towards late gaem the passive will give you like 2000 gold, which is more than enough to allow you to get an extra item. but i want to know your thoughts on building this early
