very easy if you want to trade anounymous, just go to coinmarketcap and see platform exchanger. or you send to some businesses that receive bitcoin for $ deposit, but can also withdraw $.
not sure what you mean here, can you explain please?
On shapeshift you can trade anonymous. They even don't ask for an email. You needn't register to trade there. But they are quite expensive. You have to pay attention on each step.
I will check this
You could do this on any exchange, why are you asking? if you know how to avoid scam coins, all of the exchanges are good for trading to increase your Bitcoin balance, there are some exchanges with limits on Bitcoin withdrawals, I deposited $100 in BTC and bought some alt coin, after a few days I sold them for $120 and when I tried to withdrawal BTC they stalled sending for 6 hours, when that happens you should never use such exchanges again.
If you are going to use Yobit, you should just do your trades without looking at any other coin. lol
They didn't list my activity token, bad Yobit.
Are you talking here about Yobit?
What do you mean with "how to avoid scam coins"? Please how to avoid it?
