...at that time 1 BTC was priced over 8k $, I bought 20BTC...
Then 2 months in March 2018, 1BTC was priced at over $ 11k, I was happy and decided to buy another 50BTC
I thought I would be a millionaire!
20x 8,000=$160,000
50x 11,000= $550,000
So you saying you had over $700k lying around and you were not a millionaire? And you managed to recoup your losses? That's awesome!!!
One would think such a successful trader wouldn't bother with abusing bounty campaigns and copy/paste spamming, but what do I know...
Seriously, f**k off to where you crawled from. Reported you for spam.
