I you take a critical look on the crypto market, with some expert analysis, it is very difficult to be certain of a $100k mark at the end of 2021. The Bitcoin market trends has been very volitile, and the possibility of hitting $100k may not be realistic, but hopefully, a $100k record may be achievable in early next year. Based on my little experience, my prediction for Bitcoin at the end of 2021 will hover around $56k to $65k.
