Patience is a key to success. Long term investment is the best. A lot of coins have proved that. But yet they are still coins that don't have future. But I can assure you that coins like cs,neo,ETH,btc and many more are long term investment
I agree, it is really the best, espe ially if you do not have much money to start with. So I think in this case a long term is the most suitable option
