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...
You'll automatically get the coins you are buying in exchange so no worry about converting something into something.
you sound so newbie so better do research about cryptocurrency first before entering the trading game

Yes, for the newbie it will confuse a lot about how an ERC20 token can be handled when you buy any ERC20 coins you can easily send them Myethwerwallet without any problems. When you open a new account myetherwallet you will find an address for transferring the token. You can send any ERC20 to that address every time.
