If you do not support the project or do not believe that the project will be a success then it is better to sell while if the project is good and you are sure it will do well then I guess it is better to hold for mid to longterm to let the project deliver and price grow for better profit.
There is a strange situation with FreeTon right now. Recently they ran bounty campaign here, distributed rewards. At the distribution time, tokens price was around 1$. FreeTon was in its youth. Then they start to run different promotional programs, do listings on exchanges, run competitions, more and more people gets involved in the projects. But the price began to drop when more and more people started to support and believe in them.
Hi @bitbit97, these people are called weak hands, people who don't really care about a project or product in depth, they only care about fast money (BTC, USDT, ETH) that is why they sell everything that falls into their hands for a reward.
Between the market that now only looks towards BTC and the weak hands make today TON is at a price of $0.369, I hope it goes up soon.
