Hello KingScorpio,
The altcoins you are referring to are tokens built on top of the Neo network called NEP-5 tokens. Some examples of these tokens are: Ontology, DeepBrain Chain, Red Pulse and Alphacat. To make use of these NEP-5 tokens you should have a wallet which supports these tokens, a list of the wallets that support NEP-5 tokens can be found
here.
Currently there are no transaction fees on the NEO network, however in the future the NEO network will use GAS to charge transaction fees. You can find a quick video
here explaining the basics of GAS and NEO. If the platform is secure and reliable you should decide for yourself, we suggest you do some research and make your own decision on this point.
If you have any other questions on this topic feel free to send us a DM.
With kind regards,
The Anycoin Direct team
