I asked because unless you have mentors who you can call up for directions or advice, as a newbie, you will likely learn from the experience of having more losses than gain, mostly when the market shifts and other factors happen.
Mind you that you mustn't have mentors/experts you can call to help you choose your investment or the coins you should throw your money on, if you want to understand crypto investments properly, you have to do it yourself, with adequate research you would get the right advice and information, without needing to contact anyone who you would/might continually depend on before making any move, doing things that way could get you misled or scammed.
Sometimes diversification of investment also increase your income.
Diversification of your investment increases your income if you buy different assets (that are non-crypto), it is prolly best to basically just buy Bitcoin, and buy other assets like gold, etc.
