We can't predict the crypto market in the future. we can only follow the plot and manage our crypto assets well. currently there are many altcoins that have good prospects and that makes the altcoin increasingly sought by investors. but that doesn't mean that btc will lose, BTC is still the most superior coin in cryptocurrency.
there are still eos and even Waves as a substitute for bitcoin, the possibilities are very large because market capitalization is based on consumer desires and can be changed in such a way in a few years with great intentions.
But as long as regulation is still complicated, altcoin will still try to remain a bitcoin follower to avoid the impact of investigations that are not profitable for their own coin market sentiment.
