In 5 years some of the alts we know today will collapse and new ones will be issued.
The investors will be much more than today because of the volatility of the market and the promising high gains. What is essential to happen is the use of the cryptos in our daily life.
It is mentioned before, and I believe it that the start will be from the unbanked populations of the so-named 3rd world.
I hope that the developer works more the security of the coins. Many lose their money and it is unfair.
Totally agree with that, most coins (out of the 1400 available) will fail. Sometimes probably for the wrong reasons, and shitcoins may also rise for the wrong reasons.
But in 5 years, successful projects will continue to rise because they will be actual projects, and not paper projects like they are now, so invest wisely in projects you believe in and that will have a real impact.
