Loan has side effects to investment, it acts as unforseen circumstances most time remember the market may not go as you speculate within the period of loan towards your investment, it's better to sell off your valuable property and use it than involved in anything loan because the term or condition of loan can course you pains at the end where your purpose of holding won't be achieved, except you have no plan of holding your only investing to target profit by quick withdrawal which is contrary to DCA strategy, engaging on loan to invest for me is considered poor planning strategy for an investor who uses it as medium for investing on BTC it can be for fiat system but for the purpose of long holding or the DCA strategy is not advisable at all as that can destroy your investment overnight.
Since the only way to really see a good profit on Bitcoin is by holding and we all know what holding is all about because it has to do with a long term process so getting a loan is the worst planning as an investor because the chances of paying back the loan through the investment is actually not going to be possible because it could happen that immediately the person gets the loan and invested it on Bitcoin the price starts falling and instead of seeing profits the investor is still losing and we all know how Bitcoin price fluctuations could be at times were as it will consolidate within a certain zone for a while, so if perhaps the investor is still on the losing side when the loan will be do for repayment how would he be able to repay the loan?.
Actually Bitcoin is the best investment that has ever happened to us but going about it in a wrong way could seriously get you into a serious trouble, so perhaps that's the reason why Bitcoin is not like every other investment that requires a huge funds before starting up, so instead of getting a loan one could actually use the little he or she has to start investing using DCA method because you don't necessarily need too much capital to start.
