The exchange itself was liked for its speed (does not load the system) and simple design, quick transfers, but I would like for couples such as ltc,eth,doge.I would also like the registration to be through mail, and not just the discord (many friends do not use it), I also want to say thanks for the quick answers to the questions on the discord channel, in general, everything suits me.

Is it listed on any exchange ?

It's simple really. If you want to have a chance of making it big like in 2017 then you have to pick a few coins that are actively developed and actually have a use or solve existing crypto problems. These coins will bring something new to the market. Any of the old coins that have not brought anything new or don't really have a use will hopefully wither and die off.
There is a place for smart contract coins that bring something new or a better way to do things than existing options should do well. What i don't get is why people just loyally stick to a project because it's one of the biggest or oldest. There are way better options than Ethereum out there now for instance. Remember the crypto kitties fiasco where the Eth network got blocked up and fees went sky high? Nothing much has changed since to mitigate that happening again.
Blockchain tech is truly groundbreaking and will justifiably take over how things are done in time. But again there is a better option called Dags. now if you can marry dag with multiple blockchains then you truly have something that can scale and keep scaling.
That tech is just being born right now and has the potential to change everything. A little hint for anyone who is really interested in how the future could look, take a look at the project in my signature. Read about it and decide for yourselves. sometimes it just doesn't pay to stick to the old ways
