I've been trough something similar. I was laughing at a guy who lost more then 3K$ on Poker, then I got involved in the Forex, some years ago. Tried with demo account with virtual money, reading and trading some pairs, then I double the investments for two times /starting from base amount every time to be sure what i'm doing/ and I thought BAG! I can do it too, I'm a trader. /bullshit, it was pure luck/.
When you gain some self confidence that you can do something but you really can't or don't know what you are doing it's kind of a" hold my beer" jokes.
I made some trades, lost some savings, then again went back to 0, then I made some good profit but and got more confidence, the problem is that you don't know when to stop, you become greedy, and greedier with your next good trade and you don't pay attention to the looses /big mistake/.
Everything goes exponentially same as your greed, and at the end you loose everything even more.
Aside of the money I lost many sleepless nights in watching the 3 screens, checking every time. Meta Trader had an awful default alarm sound i hated it but did't change it. Waking you up in 3 or 4 AM with this sound was horrible, I still hear it, sometimes. The good thing with the Forex is that you have a free weekends, but not with the Bitcoin.
I almost lost control over my job / I still have a small company/. Then came the health issues,too much stress and punting weight from bad sleep and sitting all the time, eating fast food. No time for friends, you are dead tired on the weekends...
I lost some money but I manage to recover. Everything was just for an year but man, had a huge impact on me.
I just woke up one night from the alarm and said STOP. Closed all the open positions and shut off the PCs. The next day I got on my bicycle and went riding for hours / it was really hard in the beginning you cannot breath after so long period without motion/.
I learned to control it, I have a family now and I have to be responsible for my actions.
Now i'm playing dice from time to time with the money from the campaigns here
