These are the mistakes I have experienced:
- Always believe in news without verifying
- Panic selling
- Buying coin when its prices are rising very fast, and after a short time, they return to their original value ( yeah, I regret buying XRP and TRON when their price is high

)
- Too greedy
If you carry out the survey, then the most common reasons of failure and loss of money when it comes to that of the investing of the money into any of the crypto currencies are none other than that of the lack of the knowledge and getting panic and then losing your patience as this then results in making such stupid decisions for which we regret later on.
