Never put all your eggs in one basket. Diversify.
Only invest what you can lose.
Always pay attention to Bitcoin.
Don’t Invest big amount fast.
Categorize your investments and look at the long picture.
Right now, diversifying means put some of your funds into BTC, the rest of your funds in a savings acct/cd/stocks/bonds/real estate.
There seems to be no point in diversifying into alts, at least not to reduce risk.
