yes, it seems that you all are right ...
I was not informed and as you said as a newbee, I bought, fortunately not too much , about 0.0357 BTC in 3 times, mostly at 0.0325, then 0.0315 and 0.3000..When I made the post, I could have sold @ about 0.031 nearly without losing anything, then I put limits, and saw the price always going down, and started to lower my limits, again and again...it was stressful as I saw the price go down to 0.029 then 0.026...and 0.025 with spikes sometimes hardly higher.
It took me 2.5 hours to sell half @ 0.02685 then 1 more hour to sell the rest by lowering again my limit to 0.02661...
I finally lost "only" 36.5 but when I look now, the price is 0.023- 0.0235...and probably much lower tomorrow and after...
I find it a pitty that the platforms like HitBtc put it on trading, without being sure that it will continue, inducing many people in error, like I did trusting the platform and with a lack of information.
2nd bad experience in just 5 days trading bitcoins, and 2nd with HitBtc by the way: after 2 days just newbee and excited that I finally started (after having heard from the bitcoin already a few years and heard investing about 1 year or 9 months), I was tired and late at night, I wanted to buy some BTG and sent 0.04 quickly from GDAX to HitBtc...but in the hurry, I clicked and copied by mistake the adress in BTG, so I tried to sell BTC to a BTG adress...
Just a few seconds after I clicked to send it, I realized...and wrote them...
They pretended that it would take a lot of "labour" from several men, to retrieve it, so they would charge me 100 $ (!!)and that it could last 1 or 2 month !!
I wrote back asking for a commercial gesture and that I would agree to pay a "fine"( a fee) of 10% but not casi 50% of my deposit and argued that it would probably be not be so difficult and not take so much time.
After 2 days, they put already the BTC to my account but only 0.02338548 from 0.04...without any explanation or calculation to justify the rate.
Following my calculations, when I received the money, the BTC was +- at 7400, if they'd charge me even 100$ =0.0135135 even if they took the course of BTC at 7375 (13:45 UTC) 100$=0.01355932
0.04-0.02338548=0.01661452
They were charging me even more than 100$ (approx 22.9USD too much), probably they took in consideration the rate of the BTC/$ at the hour and day when I sent it and the rate was lower..
Well...I learned the hard way to start !
But I can only suggest the people to be cautious and double check everything.
If everything was so clear and safe with the blockchain, why is it so "hard" to reverse or to find such a transaction? Even when the adress is false and there is a mistake , let's say in the numbers and letters or 1 missing ...where goes the money?? If there are so-called many verifications, why don't they (the verifying miners) return simply the money back to the sender's adress? Or why isn't it a verification of the currency adress or the integrity prior to confirm?
There must be a protocol set up in the future to prevent such mistakes or errors because ERROR IS HUMAN. And I wonder why in so many years, such "bugs" and improvements have not been already implemented long time ago.
Good night guys.
