I see a lot of similarities from the start of the uptrend in 2017 and what we see now. We probably see a lot of new bitcoins owners in the next few years that alone will push the price up to December 2017 level and beyond
For me, everything differs this time. First of all, in comparison with 2017, when nobody could even suspect that Bitcoin would make such a jump, now, all guys are dreaming about it. It can be the main factor why this scenario will be not repeated.
