First thing you actually need before investing in Bitcoin is knowledge, you can have the money and still end up doing the wrong thing which might cost you your capital...Take out some time to work on learning about that crypto market so that you would be able to identify things that are fraudulent so you don't fall for a Bitcoin scam...patience is key and without it you might not benefit much from it
I don't know why OP, forgot to mention "knowledge'' that serves as the basic thing one should know before investing in Bitcoin. Without knowledge, I don't think one could hodl their Bitcoin for long periods without making a mistake that could cost them a lot to lose their Bitcoin to scammers.
Actually, patience is the key to Bitcoin investment, but without basic knowledge of Bitcoin your hands and emotions can be burned up when the bearish market strikes the crypto market or scammers send unsolicited links, promising a huge return on investment if you can invest with them
