i dont understand, why are you recommending youbit for trading? they have worst support ever, many problems arenot solved many during many month, they arenot answering on tickets and mails. there are many trash coins and most of coin's wallets are under construction about one year. also i am sure, their dice isnot fair.
i advice you stay away from this site
If you have never trade till now, keep calm and study if you don't want lose all your
BTC can one still lose his btc or altcoin by trading with well known sites like yobit?
Sorry to say this, but YoBit is not a good site to begin trading, although it's newbie/beginner friendly. I started with it a month ago and I lost all my investment (luckily, it was only 0.001 BTC) on an altcoin that turned to be a scam and died.
But that's not the reason why I said YoBit is not for newbies, that loss was my very mistake, my reasons are; Very low volumes of altcoins, few orders (both buy and sell orders), good coins only pump once or twice a month, a lot of dead coins, so many coins that have insufficient data (if it has any) and the whole market volume is based on ETH.
I agree with you, yobit needs to change their behavior, they disappoint their customers, for more than months I sent a ticket to the support and they never answered me.
They do not respect their customers.
Do not forget that you earn what other ones loses.
So do not believe that you are only on the winner side.
The world is like this, you win today and the morning you lose. The most important is to have a good risk management
