Most of the new crypto coins are traded in small exchanges like Yobit, Stock Exchange, BigONE. Are these tokens safe for use, or are they a scam?
a new token listed on a small exchange is not necessarily a scam. chances are they register on a small exchange just to see an increase in interest in the token and also usually they do run the existing road map gradually registering on a small exchange to a large one.
and sometimes the token will gradually rise in price after registering in several markets gradually. but it all depends on the project wants to develop the token or not. if the project that owns the token is always developing the project probably won't be a scam
1) Have you purchased any new token which somehow been missing after a time
2) Have you observed any uncertainty in the price of token
no. i don't have time to buy or observe new tokens. it's better to choose a coin that has been around for a long time that has a good future
