I am not familiar with these coins and I think it's better to invest in coins that already have a large market cap. Nowadays many coins or tokens are pump and dump and I think we must be vigilant

The market cap of a coin is not the only thing to put into consideration when choosing a coin to invest in or trade. You need to look into the 24 hours volume and go on the exchange to check the activities going on. Coin market watch sites are also not enough.
The OP already has given insights and perhaps there are other exchanges like the one that has been stated, you should be careful.
