i think every investment have some short of risks. I can say all type of investments which you know what you are doing and have the basic understanding of the system then there you have some thing like 50 - 70% risk but if you do not have any idea about the work and you are investing because other people are investing then that type of investment is pretty risky and they are scaled around 90% risky so why don't you just donate your money instead of being scammed and gambling is not risky if you are expert in gambling many people lost their all bitcoin in gambling because they do not have enough knowledge about gambling and for me risk is involve in any activity but we need a good knowledge and information...........
