I guess fraudulent is not preventable but you can minimize being a victim if you will be very vigilant in your actions towards your investments. Doing more research before engaging to something which includes money will reduce the chances of being a victim of fraudulence.
fraud I think it has become part of the crypto currency because there is no legal force that protects it so we ourselves must be able to choose which ones produce and which ones are fraudulent
I am agree, its because there is no government regulation. Its makes every people can create their own coin or token and sell it to any one. If fraud always happen in crypto, its make people think crypto is scam and people will not interesting to investing their money.
There is should be government regulation to regulate ICOs or project and if that happen, i think investor confident will increase and market will more attractive with more legit project
