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.
For me there's a lot of option to not invest of any loans jus to get bitcoins to hold for an investments. Yes it's right thar bitcoin really needed to be saved for better future purpose, and having loans is just a stressful obligations to pay for and you cannot have the assurance for your invested profit to benefit you in an instance. Btc price will not increase immediately, you may encounter more fluctuations and might provoke you to sell at an early stage.
