Bitcoin and Crypto Talk (Merged)(includes NFT)
All very true SC500, but somewhat of a buffer on BTC is that you can convert it to so many other currencies which are being developed with fundamentals. ETH with its contracts built in makes for a great vehicle to track things heretofore used with paper such as titles, liens, warranties, etc. Then you have MS going in with IOTA to provide a system of purchase for the internet of things. Already there are music, gene sequencing, travel planning, options too.
BTC could very well collapse, but the Dow dumped half it's value only a decade ago and could again. I wouldn't bet my retirement on it, but if you have some extra cash to speculate with you might be able to retire earlier than anticipated.
