My first coin was OCtoin, I wanted to laugh at this coin because I was trapped by the many media advertising this ponzi coin, then I replaced the coin and rented an ethereum mining pool.
Surprisingly, after 3 months the occ coins were listed on the exchange, the price of 1 coin became $100 and I lost my chance to make a profit because my coin could not be withdrawn because it has been frozen to rent ethereum mining.
1 year later, no news from team members and i left ethereum and occ coins i have on their platform.
From there I started to learn how to look at a good and honest project, it was very complicated but from experience I was able to learn to make investment decisions.
