Bitcoin price is increasing so fast such that some people wish they borrowed and bought bitcoin at 29k some weeks ago

I want to know if it's much risk to borrow and purchase bitcoin like it is to trade bitcoin. However, the market is pumping, and it may seem like a good move if the loan is not for lunch, rent, and family bills which account for our daily needs (That is, my daily needs have been taken care of). Thus, timing is another criterion to discuss. How can someone know the perfect time to pick such a desperate gamble? We win or lose in trading or holding bitcoin but, I presume with the help of experts in this forum who have gone through thick and thins in this market, good guides or rules can be shared for users and newbies in the forum to have a grip on the market and know if borrowing is appropriate. It does sound thoughtless but, borrowing is part of the business. And we must prepare for the best as well.

Thanks, I'm ready to learn.
