Think twice, before you start investing your BTC. At least if you hope to invest in Bitcoin-related opportunities. A very large number of "investment opportunities" in the Bitcoin sphere are scam. Almost the entire remainder come with extremely high risks. Even if you consider lending out your BTC individually to earn interest, the probability to be scammed is barely worth the risk.
So my simple suggestion is: Don't invest your BTC. Just hodl. If you want more Bitcoin, work for them. Offer your skills. Or sell something you don't need. That's far more effective and less risky than "investing".
