Some people said it is more profitable to buy those coins or tokens that are still undervalued compared to those already expensive ones...so I started buying undervalued ones and hold them for a year..is it a good decision to hold them for long term ..which tokens/ coins do u prefer?do u prefer those in top 100 on cmc or the ones newly listed but u see the good future too..
Yes, it is profitable to buy undervalue coins, if it is well researched and you monitor the market uptrends, or else you end up in the village.
Similarly, its not always good to hodl on the long term, just hodl, sell, buy back, etc trend it helps
You can give a try to litecoin, neo and waves, they should give u back your profit in couple of weeks, if you monitor it closely.
Good luck.
