I thought my $120-240k was very optimistic. You think it’s possible for BTC to reach $400k levels this year?
I have been keeping track of the predictions of six independent “influencers”, the most optimistic being one that predicts a high of $387K by 10May21 and an end of year value of $286K (Crypto Casey). Personally, my own (linear) business plan prediction is $150K by year end, and the one I trust the most of all the influencers is that of Max Kieser who has it at $220K by year end. I have watched Max Kieser for over a decade but never picked up on his penchant for Bitcoin until the middle of last year. In summary I think your range estimate is wholly realistic.
BTW, if BTC does reach $400K by the end of this year, it is going to be very hard to HODL - may have to sell half (LOL). 
Same for me LOL
There will be a massive selloff if this happens! Actually, I think the selloff will start at 100k haha. I can’t imagine people still hodling at that price!
