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.
Joining platforms is really good but hope u know that most platforms now just want to scam people joining, it will be difficult for you to see a legit platform, but platforms like Bitcointalk is really useful because you can interact with people and you can learn here without pay amount.
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.
I know it’s unsafe to invest in only a single coin, but it’s better I invest in only bitcoin than investing in most of the altcoins which we can find in crypto space currency, you might think a altcoin is a strong one but don’t be surprise that those coins you call strong coins are the once that are going to crash in the long run. I can invest everything in bitcoin because I have the confidence that if I can hold bitcoin, then with time bitcoin is going to pump, I see bitcoin as the only coin that I think worth holding for long term. I don’t believe in all those altcoin so I will rather go all into bitcoin than spreading my money in altcoins.
