In my opinion buying and selling is not a good choice on this exchange, but if you follow a bounty project that lists tokens on the exchange there is no other choice but to use its services, this exchange has many weaknesses in it, they carry out system maintenance quite often, even maintenance they continue do not give any guarantee for a better future, I think if you do not follow the bounty project, then it is better to buy and sell coins on other exchanges, which are more convenient and easy to access.
The advice you have given is very appropriate and can represent for everyone who is still using this one exchange, because if the token from the bounty makes several listings on the exchange and one of them is this exchange, then the choice must of course be set for the others, but if it's just one like Foobe, I think everyone will be very forced to use this exchange to be able to sell their tokens before their value is completely lost.
