Which crypto do you trust more, the one that is traded freely and nobody knows where the rate will go tomorrow (like Bitcoin) or the one that is under control of its developers (like Ripple, more or less)?
Where you would invest?
Trading is the best way to make a profit. After businesses like ICO, IEO, and STO, we need to be smarter to define projects. But if trading on a good coin like BTC and ETH will be safer.
But in this industry, all jobs can make money. So that every opportunity that exists such as ICO, IEO, and STO, should we be able to utilize it well to make money.
