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.
your holding more ethereum right?lol bitcoin will never be replaced this great coin will remain dominant until this whole thing gone,or maybe grow more.but ethereum is one good coin and deserves to be respected.anyway for the prediction OP is asking i guess the best answer bitcoin will completely hold the top and may reach $100,000 after 10 years
