As I've read the entire thread, the majority are suggesting not to take a loan. I voted for that as well.
We can take some loan for a reason and even for trading but because this is too risky and less assurance that we can make a good profit (or even to lose all of it), it is not really a good option to take.
Anyways,
I hope OP has to come back in this thread and read our opinion. But of course, it's up to you if you consider our opinion or not as the final decision is yours.
Agreed with most of the votes on here. Now, it is not a good time to take out a loan. This is because the market is not yet clear and getting out a loan which you can't repay back in time will be unnecessary stress. It also depends on the strategy one applies on this loan, though usually given the market situation one would find it difficult to profit and repay back their loan.
That last statement carry the loads, it depends from the strategy that you'll going to use, since OP already have a good amount of investment it seems that he's just trying to add more entrusting his fate to this business.
It's understandable that if you have a wealthy family and if it's for real tat they'll extend their hands to lend you more funds for your crypto investment, you have to balance your decision-making.
Long term holders way back are all achievers until now, they managed to trust and harvest the fruit of their success.
