It depends which type coins portfolio you have,If you hold stable coins it can be profit oriented in long run.Buy cheap and hold surely will earn good profit and will be beneficial.
Correct since there are type of coins which has questionable use and some of them are totally shit so selecting the correct net with existing running platform is a must for choosing so that risk upon holding some coins will be lessen and chances to gain will became more higher. But we shouldn't expect hard upon holding but instead we should look for good experiences on it so that we may know the flaws of each actions we take.
is that any stable coin? I see all coins have a very high fluctuation, maybe it depends on the coin you choose but is that coin has a great future potential or not, for example if you buy and hold Ethereum for the long term. it is not a problem because this coin has great potential in the future, yeah its depends on the coin you choose mate
