1. Investment scamming: a scammer will tell someone that there's an investment available which there's little or no risk involved and one will get his return in Bitcoin, they make it real and some set of people who always love quick success accept and they get scammed, they may also introduce to you fraudulent mining operations so let's be careful.
this type of investment scam is what people need to avoid... because in the current bitcoin trend, many scammers take advantage of this by offering a type of bitcoin investment that has minimal risk with a return of hundreds of percent.. and that usually targets ordinary people who do not know for sure how to invest in bitcoin and want to get rich quickly. these scammers take advantage of people's innocence by promising high returns, but in fact it is a scam.
people need to know that there is no such thing as a fast high return on bitcoin investment-- all of that takes a process and people need to learn the right investment knowledge to avoid this scam.
