Those people should blame themselves for doing that action that's really not suggested of borrowing money to invest in a highly volatile asset. They know that for sure but probably they've been into FOMO and did that last thing that they shouldn't as they've got no choice and thought that they might be too late to enter. We saw how many of those folks did commit this on the 2017 bull run and then regrets when 2018 has entered. Investing in crypto is a high risk and high reward market but you must know what you do before investing.
