Don't expect that you can buy bitcoin with $50 bitcoin will never get back to that price its impossible to happen right now if you can realize and think deeply who those support bitcoin and there are countries that bitcoin are accepting and you don't realize many business online are accepting bitcoin?
and many people are using bitcoin so its impossible bitcoin price will drop at that price.. And i think devs are holding a funds to support bitcoin when never the price is drop below 2k look at the fluctuate there are someone are sill supporting bitcoin just to stay the price at 2k value..
