I think it will not reach that price even $50,000 because of the high fee, but if there is some kind of technology that can reduce the fee of bitcoin, then possible it will reach $100k.
For high fee problem, i think we can just wait and believe for implemented of Lightning Network, "The Lightning Network is a system of smart contracts built on top of the base Bitcoin Blockchain that allows for fast, cheap payments directly between two parties." source
MediumSo far i seen, many party now against Bitcoin, idk what's going on, are a discussion to make the regulation going to stuck?
