sorry I am bit of a newbie so my question is if I buy for example BQX on Binance or Utrust on Kucoin with BTC this altcoin automatic are converted to tokens or do I need to convert them to some form of ETH token before I send them sorry is a bit of a silly question but I just want to make sure before I send them thank you in advance...
BQX and utrust are erc20 tokens, after you buy them on exchange you will need erc20 compliant wallet such as
https://www.myetherwallet.com/ to send them to it, you don't need to exchange them to etherum because if you do then you will have ethereum and not erc20 tokens.
May I suggest you to do research about:
1) How to use ethereum wallet
2) How to send ETH
3) What is erc20 token
4) How to send and receive erc20 token
