I think no one can replace bitcoin because if there is, it should already happened long time ago. We all kno that boitcoin is still dominating the crypto world and I think no other coins can do that.
Yes, the same to you mate there will be no other crypos will replace bitcoin in the future even if theres a lot of altcoins launching with high potential like denaro, ripple and others. bitcoin has a lot feature and until now its continues developed its market abd I guess in the near future bitcoin will be more valuable by many people.
This may be uncertain, too. up to now there is nothing that can replace the bitcoin can be so because it doesn't yet exist that could exceed the bitcoin systematically. so it is not impossible but is not alone. But if Bitcoin continues to grow the better, certainly also will be quite difficult for another crypto to pursue it.
