If you don't have a big budget to spend.
Investing in cheap and promising cryptocurrency is a good strategy for the long term.
You can get more RIO if you invest in cheap crypto than if you do it on expensive one like ETH
This is my logic and I present 5 cryptos that are very promising and solid blockchains.
The first one and my favorite is Dogecoin because is's broadly established fast has a cheap transactions
Second one is Digibyte . They have the potencial to moon like GamePlay.
3 is Reddcoin because it is potential winner of even smaller social media sites start using it.
4 is Burst because like Doge is very fast and it is used in many casinos. And if more casions adopt it it will go to mars.
5 is NEM . I has the ability to integrate with big and small corporations and business , plus many more applications.
