The crypto market especially altcoins can make you rich very fast but it can also make you poor real quick. Last year I started to became more contented and realistic that 10% above is already a very good profit. I only hold few long term coins now like bitcoin and ethereum.
Getting some profits, 10% for example, is already good and most of the time I will sell my coins whenever I got such profit. And then I will wait for some time to start buying again, especially when prices move down.
that is the best thing to do, as long as you can earn set aside the fees from it and keep your profit in and circulate you capital and vice versa, we dont need to earn double money we can earn even a little percentage and we should satisfied with it.
