I believe that there should be a product first. One idea is not enough today. It hurts a lot of scams that play on the trust of investors. It is worth a careful approach to investing in cryptocurrency. Because not many coins in the future will be popular. I am sure that in 2019 and 2020 some of the coins will simply disappear. I hope that your project will not belong to this number.
I also think that the crypto market will be a global purge in 2019-2020. During the depressive 2018, many projects left the market. only strong players remain!
