The term "Cryptocurrency" was originally coined for Bitcoin and Bitcoin is also now dominating the cryptocurrency market and has a very large marketcap that beats all altcoins.
If Bitcoin now has success, then altcoins will also follow suit and of course, various countries in the world will adopt it very easily because the ability of cryptocurrencies is really very interesting to invest and take into account the benefits.
The prediction must exist because it has the possibility but to be precise, Bitcoin is difficult to predict the price direction, whether it's up or down but if in the short term it is like that and for the long term Bitcoin will definitely continue to rise in price.
