We always have regrets during these violent cycles: "I could've bought cheaper", "I could've sold earlier", etc.
We really cannot accurately predict crashes/booms every time as unexpected things almost always happen. What we, crypto enthusiasts & "veterans", know is that it will not be the end of Bitcoin or cryptocurrency, it's still in its infancy BUT we have seen an unbelieveable rise of market caps, prices, total amount of crypto investors and a rise of the number of existing cryptocurrencies like never before.
I think it's naive to say cryptocurrencies will never go down. Any market has its falls and rises, but it's almost impossible to have an investment that will get you profits forever.
I don't want to convince anyone to sell, buy or hold, but I'm sharing my thoughts on this so-called "crash". I will keep holding and buying although my total portofolio is 8x smaller than just 3 months ago. Look at all this immense projection of prices and the extremely rapid growth & adoption of cryptocurrencies. This is a different kind of bubble than those of real estate, fiat & other industries.
