Altcoins include ethereum,polygon etc. Already heard of dying of altcoins. Many peoples invest in different platforms. Some people hold ethereum polygon bnb etc. But their prices don't rise much. Are they better to hold and invest than Bitcoin?
In terms of holding or anything else you could think of that would maximize your cryptocurrency for more profitable opportunities no coin could withstand bitcoin or come near where bitcoin is because other cryptocurrencies has Higher risk in terms of holding so why should we hold what is more of risk than the benefits we stand to gain, bitcoin could give that desired profits and make it permanent unlike other altcoins which easily fades away.
In my opinion Bitcoin is the best to hold.
That's just it all, no other thing is attached than this, holding other cryptocurrencies aside bitcoin is like holding nothing because you could loose everything before the end of the day and the whole story turns around from what you least expect to happen, which should be the worst you should fear.
