In long term investment with altcoins your asset will be locked for years which means you need to be patient for a long time of not withdrawing your asset but in exchange of higher rewards. Market moves up and down but the long term investment will surely gives the you high profits in the long run. However, knowing that there are thousands of altcoins available in the market today, so, you need to choose the right altcoin for you that will also last long in the market.
Exactly! Being committed in a long term investment isn't an easy one to pull of, because it really needs extra patient to make that investment gain some profit. Altcoins is almost the same to bitcoin's nature, the only challenge is to having a research for you to pick surely that atleast 3 top performing altcoins before locking it for years or depends on your timeline but since altcoins doesn't perform as much as bitcoin does so practically hodling it for atleast 2 years is somehow needed to gain that expected profits you want.
