In that case I will too prefer you to invest in ICO's as it is the best possible way to earn high profits in a short time but be careful when investing in an ICO as most of the ICO's are just here to scam.
Read the whitepaper, look if they have a valid team, what is their purpose and many more things you need to research on.
And lastly I will still say do not put all your eggs in one basket so invest in 2-3 ICO's as it is safer and more profitable also.
