Base on my experience when i return or deposit again after i lose my deposit will make it even worse instead of winning back my losses, i lose again the new deposit. So what i can advise to you is do not try to win back your losses, if possible stop gambling even if it makes you happy for a bit of time, i prefer keep holding bitcoin and in the future it will make you more happy than gambling your money.
Sometimes I lose it faster than first deposit, only few times I was able to win back what I lost.
After losing money it is best not to try to recover money, deal with your lost and move on, try your luck next time.
Trying to recover loses can lead to more and bigger loses and troubles.
Yes it is very important for winning your money back. If you have not enough money to bit again and again then I will suggest not betting lot of money at one time. Bit little money and of you lost you will have more money to play again and at last you will win.
It is also not possible to lose every time. But be patient and cool while gamble and look at the conditions which are your favor or not. Never give up and fight till the end.
