Perhaps the errors when buying crypto currency are such as follows:

1. Don't just easily get attract to buy token in every ico project.
2. Avoid buying shitcoins that has no volume in volume in the market.
3. Never listen to any FUD news here in the forum about the coins they are announcing it
    because they are just hyping anyone here to buy their token.
4. Never join in any PUMP and DUMP group here in the forum or in telegram
5. Don't follow your emotion always, just observe it first before anything else.
