Thats are ERC20 tokens, so you can store them in every Ethereum wallet - even here https://www.myetherwallet.com/
MyTV is not traded yet. IEO was postponed and (unofficialy) will take place in December 2019.
IEO and later listing will be on Liquid, LEX Exchange and one more still not announced. Trading after IEO will be also on Latoken.
About trading 4ART - exchange still is not announced.
so you have the MyTV tokens in your own ETH wallet ? please can you post the address so I can confirm - not worried about the 4ART bit at the moment, im trying to value the TV things with the man eater as president and the police line up as the team on the website.
MyTV announced IEO before and postponed it, but there was possibility to deposit tokens on LEX exchange and Liquid. I had them on this address:
https://etherscan.io/address/0x0dce8f8e8ac478c9a4744e87fa3483e2a845b77e#tokentxns
and now I keep them on Lex exchange - it is my deposit address:
https://etherscan.io/address/0x0dce8f8e8ac478c9a4744e87fa3483e2a845b77e#tokentxns
and here is LEX exchange cold wallet:
https://etherscan.io/address/0x3881d012d6322105bb477c5aa8f4aa32dd108980#tokentxns
Give me few minutes, I will withdraw it to my wallet.
EDIT/
(( I can not withdraw it now. I submit ticket, but my friend own that amount of MYTV in his own wallet and can borrow it to me. His address: https://etherscan.io/address/0x542196716f83801f4fffbc1fb8ede8b479b481ed#tokentxns
He own on this address 40500 MYTV. If we agree with the loan conditions, he'll lend me 32,500 until I withdraw mine from LEX.
