Altcoins to an extent may have their performance in some extent to out weigh that of bitcoin, nevertheless, we cannot because of that assume that they are more profitable or safer to invest than bitcoin, as many have understood the nature of some of these altcoins, we have the memecoins and memetokens and they all have high risk on investment in which if they lack the financial backup on investment to the crypto project, it may fail and turn a scam and investors are prone to loose everything invested on such altcoins, but there's none of these in bitcoin network, so its a decision of going for quick and higher money or little and steady income and security in bitcoin.
