I think bitcoin will cost more than$ 50,000 in 10 years. Also, it will no longer be the first cryptocurrency for capitalization. Ethereum will take its place because Ethereum has a working economic model. It's not just" digital gold " like bitcoin.
Well, bitcoin will surely rise and fall anytime. But let us all hope for the better future of bitcoin and i am also hoping that bitcoin will reach at $50,000 as early as btc can. I hope it is possible this year but with the flow of btc price now i guess it is imposible this year.
