Another gateway to keep abreast is to get connected as a member of an active crypto community or platform. Having membership of different communities is an added advantage but make sure they are a genuine platform with a good history just like bitcointalk.
Not bad to join an online community, but be very careful and avoid scam.
As a matter of fact, it's very unsafe to depend on a single coin. In otherwords, invest into more than one token by spreading your investment into potential coins but be careful not to invest into pump and dump coins. Above all, make sure to maintain risk management in which ever crypto asset you are investing in.
It is very safe to inbest in only bitcoin than going for altcoins.
