I am disappointed with the project in crypto, many bounty projects cheat their members, they make sweet promises to members after their project is successful they are free from responsibility for making new regulations and there are projects that don't want to distribute their tokens because they are afraid to distribute tokens to bounty hunters the price of their tokens down.
That's why people always advise to invest in Bitcoin, Ethereum instead of greedy looking for big profit from shitcoins.
You should avoid participating in new projects without doing any research, cryptocurrency is an open and evolving environment so there is no way to prevent scams here.
The only way is to be fully equipped with knowledge and best of all to stay away from the temptations of new projects, focusing on Bitcoin and top altcoins.
