It's advisable to first refrain using personal loan to invest our bitcoin. We doesn't want to invest our whole btc in loan. We just invest little bit of btc into loan.when we get income or lose it our btc,it doesn't a matter.
In general, I prefer not to get involved in loans in any way. It seems to me that today Bitcoin needs to be earned and saved, but no fights should occur. You need to think about the future and keeping bitcoin is the best that can be.
