People who keep bitcoins and invest in altcoins are basically the worst fools in the modern age, because investing in bitcoins has the most benefits and the least risk. Those who have invested in Bitcoin have largely succeeded, and those who have invested in Altcoins have failed because Altcoins are constantly being wiped out of the market.
I don’t insult anyone that prefers altcoin investments over bitcoin, if I can advise them about bitcoin investment and they don’t listen, then all I do is allow them to invest in whatever they want, they have a reason for that, so they shouldn’t be insulted. But the risk in investing in altcoins is just high, if anyone is holding a coin for a very long period of time, then it’s just better to invest in bitcoin and not altcoins, because anything can happen to altcoins at any moment, and it’s going to be painful to hold a coin for so long, but later to discover that everything is gone or doesn’t even have value when you want to sell.
So it’s just better to invest in bitcoin and have peace of mind. If you're investing in bitcoin, just make sure you don’t leave your investment on exchange and make sure your wallet is properly secured, and you won’t end up regretting why you invested in bitcoin.
