First, some context: I am in no way a Bitcoin maximalist — I think there's some value outside of Bitcoin, but ultimately BTC is my 'main' crypto holding and every profit I make with altcoins has always been exchanged back into BTC.
These values outside bitcoin are very unpredicted to know if it will come and very risky. Normally the value of is unpredicted but it is certain that value can be obtained at anytime, but in altcoins I think it is different. Their is no much different between altcoins and gamble, I think with the experience I have with altcoins I don't think anything will make me to take altcoins serious for me to invest my money because values in altcoins are no certain, it is very possible to even lose all money in invested in altcoins.
Bitcoin is always the home of value, no matter how people try to get this value outside bitcoin at the end they still turn back to bitcoin to look for good value.
I have to agree that it’s quite difficult to achieve good profits with altcoins, that sometimes you tend to think that it’s more than luck like gambling than real investing. But if you eventually hit the right coins and invest in it, rest assured that you will make some decent profits that would sometimes exceed your bitcoin expected profits. However, this is rare to happen now as most of the new altcoins that are out in the market have turned into fake ones, thus sticking into bitcoin is what the majority are doing in order to avoid more losses from altcoins.
