VECHAIN (VET) is a good choice. I have been observing for a while. Although its technology is not very good, its price will continue to rise, indicating that its supporters are very strong.
It is very likely to be an air altcoin. It is difficult to see its development potential only by looking at the current price situation. On the development prospects of users and technology, etc., it is better to invest in bitcoin and ETH rather than VET which project may sell out the it at any time.
