I will definitely try to buy more Bitcoins as soon as I get the chance to buy them at a lower price. In that case, if I get the chance to buy Bitcoins at $500, it will be a great opportunity for me. I can only dream of buying Bitcoins at this price, but I don't think it will ever be possible in reality. Even if Bitcoin's price is not $500, if it drops to $1, I will still believe in Bitcoin and buy and hold Bitcoins. I don't believe that Bitcoins are an asset that will ever be scammed. So no matter how much the price of Bitcoins drops, I will never be afraid of investing Bitcoins.
If bitcoin suddenly drops to $500 amidst the rapid growth of interest and you say you really want to buy it in large quantities - then think two things. First - what caused bitcoin to fall so low - second, what can save you from the loss when 99% of people lose faith in bitcoin?
I would say that it is almost impossible for bitcoin to go down to $500 unless something major happens, like a technical failure or something. I don't believe bitcoin can go back down to $10K when it has been around $110K to $150K - so $500 is not the most reasonable price I would expect. Even in a bearish cycle - I don't think bitcoin will lose 90% of its highs, that won't happen in my opinion. You can correct me if I'm wrong - but let me know if the above statement is correct.
You can certainly expect bitcoin to drop 50% to 70% from its high price during a bear cycle - but losing 90% of its price seems less likely. But who knows - we never know what the future holds, but try don't put all your eggs in one basket.
