I'm pretty confident that BTC wont drop down in price to the point that we'll spend thousands of BTC just for a "single pizza". Analyze the situation carefully OP. The market is influenced by supply and demand, in each passing year BTC is gaining more and more popularity from people across the globe. Even popular people are now acknowledging its value, take Elon Musk as an example. BTC currently exceeded 20k, it was recently priced at 50k. Of course it wouldnt stay that way, as it is unstable. Now it is back to 30k but atleast it hasnt dropped down drastically.
