If you Invest into Crypto make sure to spread your investment over multiple coins.
I use the 70|20|10 strategy.
It s really simple: You Take 70% of the money you want to invest and spread it over the Top 10 coins of coinmarketcap. Bitcoin, Ethereum....
20% of Your Investment you can spread over coins within the TOP 100 that you think have a really good Community and Technology .... steemit for example.
10% You can Invest into new coins or ICOs. I take a look at the Teams behind the ICOs to choose good Investments there.
