yes, I think it's worth buying a coin that costs under 1 $. if I have a little capital, I prefer to buy a cheap coin. but we before buying should see how the potential coin is in the future. not a few people who earn money from cheap coin trading. for example ripple, ripple market movement is very crowded, and I think ripple is one of the coins that are cheap and worth buying for use as trading or also used for investment. because in my opinion, the good coin is not judged from the price, but judging from the market movement of the Coin.
