Hello. I see different platform like nexo, blockifi, etc... that can borrow you crypto or stablecoin. I'm here to ask if you have a strategy for example you borrow btc with an interest rate of 6% and then you use it on defi with 8% APR. Thanks for helpful. 
You really take high risks, because taking a loan just to invest in the crypto world is a mistake for me, yes, because the risk of investing in the crypto world is very high, therefore it's better to invest with your own money, and don't follow ICO or IEO projects which is not clear.
