2020 means 2 more years, enough time and I think have many important things will happen in the next 2 years. crypto will continue to be popular, help everyone and can solve problems that we often encounter today. indeed there are many obstacles and attacks from the other side, but the right will win and according to the will of the community.
That is actually enough time indeed to expect the best to happen. I am sure by then we should have already started getting close to mainstream adoption and there would have been huge development in the crypto sphere. Cryptocurrency is the future of money and it is good things a whole lot of countries are beginning to accept that fact.
What is important is to know that as long as we start seeing real life usage across board, things would have changed and I believe in this coming years, this is something we will eventually get to see anyway. But honestly, I expect a lot of coins to end up dead in the long run and those are the ones without a real life product and all they are just good for is pump and dump in the crypto space.
By 2020, I expect a lot of changes in development to have occurred. Probably by then, the scaling issue of bitcoin would have become a past, we would have started seeing many avenues that permits real life usage and certainly with things like this, we will get to see mainstream adoption. Now, in cases like this, only coins or tokens with product will be able to stand.
