I think it's mostly a bull wave and if you see the market then you can see many alt coins are also getting pumped since last two days. There's higher chance that we might see more such upward movements in coming days. I think we should expect to see higher value of Bitcoin in next few days if the upward movement gets intense. If somehow Bitcoin crosses $85k value in next few days then it might not fall back to $65k again.
I would not jump to this conclusion that fast, because it has dumped before and it can dump again, even if it touches the $85k or $90k. We can only conclude the final decision after it stays above $80k for quite some time, and once this range turns from doubt into confidence, which will happen when it becomes a strong support zone, then we can say now maybe it won't hit $65k again.
So that means, the market has come out of the bear zone, but I would definitely call it a bull market even if alts start to catch up. BTW, they are catching up.
