However, IMHO, next bull would probably be the last one (or penultimate) driven mostly by halvings because at some point we would have to transition to a situation where miners make money mostly from tx and not from block mining.

I think a lot of folks like myself invested/mined when bitcoin in 3 figures.
Then watched their stash balloon to 20k/coin and didn't sell thinking
 "oh it's gonna be 50k in a month or 2 . I'd be foolish to dump it now!!!"
yeah that was me....But still holdinghodeling ..still way up despite the 80% crash.
But damn! I left a shitload of doe on the table.... (I'm not the only one, that's for sure)
No worries... it could be a lot worse.. I pity the grandmas and taxi drivers that bought at 19k.
fomo can be deadly in crypto.

Anyway, as always, as Jimbo says.... GO BITCOIN

This is my take on that chart that infofront posted after some consideration. I think the next peak will be in the 2nd half of '21 in December. If this is any indication then we will have one week between now and mid-summer of fairly extreme volatility that will make a yearly ATL before trending upwards. Many assumptions and a fair amount of bias here so do your own research.
