yes ,, now the price of bitcoin is very high. can certainly be one of the factors that can affect the existence of altcoin including price issues ..
but if you are going to invest in some altcoin ,, you can find it very easily.
so much for now new coins are popping up and have entered the list on various apps, just look at the coin market cap app, there are lots of coins and prices so you can monitor for yourself which coins are good for you to invest.
my advice, you can try to invest on altcoin VOLK ,. if you join today, you can make your life more fun to invest in VOLK.
good luck ..

I think if bitcoin becomes legal in all countries it will further facilitate access to payments throughout the entire transaction process.
otherwise it may be the world's major currency.
but with a high level of risk due to the bit sensitive bitcoin prices, I think it is still difficult in the near future if bitcoin becomes legal throughout the country.
