If it crosses 15k then I think it will be enough for this year. BTC has already suffered the price because of the epidemic and other financial crises. The market looks stable for now and hope this will be work as support and price will go up from here. But we can not predict the future so other people may not agree.
There is no limit for bitcoin and 15K is not a big target compare to what we are witnessing these days, the pump in the market. I think if this continues we may see 20K in this year and even 25 K is possible because as we go higher there will be no or less resistance.
the potential of bitcoin is indeed unlimited. it's just that the price of $ 15k looks good enough to be achieved at this time. however, we all expect a higher price, but I'm also waiting for the price of $ 15k for bitcoin. I am pretty sure that achievement will bring the world of crypto back in the spotlight.
