Which coin do you think would be the best in the long run?
Please recommend the coins.
I don't want to buy for short investment.
There are so many blockchain projects in the world.
What project looks most promising?
If you are looking for a safe investment with good gains go for large marketcap coins. You should go with Ethereum (ETH), Ripple (XRP), Litecoin (LTC), Stellar (XLM), Cardano (ADA), Holochain (HOT).
If you are looking for big profits you need to take risks (only invest that much you can afford). You can invest in small and mid-cap coins like DOGE, WPR, MWAT, REQ, NPXS.
