It is great story for people who have zero patience and sell immediately when they just got their tokens or 15% profit for example.
But I had such situation when patience played the role against me. I had one coin that was $0.1 on ICO. Some coins I had from airdrop but the most I bought. And this coin went to $1. I got x10 and it was a lot of money because I bought for almost all that I had that time!
And I decided not to cash out but hold. It began to dip. I hold. It continue dipping. I hold. Now this coin is $0.03. Make your conclusion
I think you need to have lost and profit management. patience is necessary, but if we already get a profit, why not we money some of our initial investment or 70 percent of the total funds in the coin. For easy, make a target when we will attract or withdraw the money. I just realized this when I also experienced similar things and things where I rush to sell coins. I will cut the profit when my token ICO was touch 2x-3x.
