No matter what you choose to invest into diversify your funds, as they say don't put all eggs into one basket.
My favorite would be Bitcoin and majority of funds I would invest in it. The rest depends on your preferences. But don't think that once you've invested the funds the work is done., you have to watch the market all the time to know what is going on and to prevent possible losses.
yes also you need to remember that bitcoin or any other cryptocurrency is not a place to make you rich overnight.
first of all that is the principle, keep in mind, otherwise if you fall for that high return offers just like a high yield investment program you won't get any long term benefit. learn slowly about the real financial freedom and connect it with cryptocurrency.
have 40% profit a year in crypto is so possible , again you need to analyze by yourself which one you will invest in , as we can only encourage how to do it not which one , pretty obvious it will make the difference!
don't go all in for your first attempt , you will be expected to make mistake so becareful .
