In the current crypto market, the value of Bitcoin is compared with the value of AltCoin. It is never possible to get that much profit by investing in altcoins, most of the altcoins are scams. However, by investing in Bitcoins one can avoid facing losses. If the Bitcoin market is down, it will surely rise again. So Bitcoin has the most investments compared to altcoins among the current cryptocurrencies and the future of Bitcoin is the brightest.
I agree with your opinion ... yes indeed bitcoin is the most appropriate to be used as an investment vehicle. indeed most people invest in both bitcoin and altcoins. but of course we have to love our money, don't let our money run out because of investing in altcoins. and I see now that bitcoin trading volume is getting better. and in my opinion now many people are starting to give up investing in altcoins because many people have become victims of investing in altcoins.
