The best time to invest in anything, is when you have the funds and are ready to loose them. Never invest into anything that is uncertain without being ready to loose it all.

With that said though, BTC might go a little lower before bottoming out. We might see a fall down to the mid 2k, and hopefully a bounce from there. But do your own research and studies, do not bet your money on other peoples beliefs, no matter who they are! Cause at the end of the day your money is yours and your decisions are yours.

FYI, im swooping in on every drop right now
