What you say these have received good returns to investors, so can't as low cost, you can invest in some of the ICO project, and then select the hold 2 to 3 years, so when the time comes you almost is the lowest cost.
What do you mean by that question? If you want a
little capital, you will automatically also get a little profit. You must be willing to sacrifice a lot of capital and lots of time to invest. There are various Altcoins you can collect in small amounts, but to get a
lot of profit, you have to wait a long time. And in the midst of that waiting, all possibilities can occur, including loss. Instead of risking a long time for a small amount of capital, it's better to bet a lot of capital to make a lot of profit. Many people can even profit in a short time, but they need money for a
lot of capital. Hope you can be wise.
