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
When you emphasis knowledge before investing, it makes me wonder what you mean because to invest in bitcoin, you just need basic knowledge of how to buy, withdraw, chose a good wallet and how to protect your investment. This is all you need to get started, every other knowledge can be gotten while already invested in bitcoin. If you wait to know everything about bitcoin before investing, you might up not investing or missing the opportunity to buy at cheaper prices.
