In my years of experience with bitcoin there is only one effective way to avoid scammers. In joining ICO even if you do your research you will not know that they are scammers until the ICO is over. Even if how many preparations we do or make in the end we still end up being a victim to scammers. The best way to avoid scammers is to no invest your bitcoins. Just hold it in your wallet and hold it for a long time and when the price is right you can sell them and you will have a good profit.
That's right. I think although it was useful to keep those above-stated means of protecting yourself from scammers, the best way to actually do it is to be disciplined and aware enough of what to avoid and stay away from. As this market is a big profit-giver, then it would be subjected to schemes and scammer attacks just for them to get some of the profit of people who won't be careful enough to guard their investments. Therefore, one should always be vigilant with every move he makes to make sure that before doing any act, he is secured.
