For me it's a big YES!! Because most of the coin boomed after several months or years, then it's a win win for a hodler or for long term investment. You just have to be very aware in the cryptoworld, 'coz we don't know the different factors that might affect the stability of a coin. So you should be very aware of that. Always keep on track.
if you only savng big coins like Bitcoin and Ethereum, you don't need to hesitate to hold on for a long time, because the price will definitely go up, just need a little patience. but if what you buy is a small altcoin that doesn't have high trust, it would be better if you do the analysis first before holding it
