Greed is something that is not advisable in whatsoever one is doing, cause it can cause more harm than good, be it as a trader, investors etc. Being contented with that little profit made can be more satisfactory, than facing big losses or being locked up by the market downtrend.
Taking loans for investment is one of the most dangerous things an investor (small investors) will want to take part in. As a crypto investor, trader or enthusiast, you are not advised to go to money lenders for making investment. Big investors can go to money lenders, because they know they can pay back on or before the due date of the loan.
This I will say is the ignorance of a newbie in the crypto community. Acquiring knowledge and investment advice in crypto related forums can be very helpful to avoid situations like this.
