I started trading in 2017-18. At that time I used to trade at bittrex, now I guess it has shut down operations. I am assuming at that time Bitcoins were at 600-700$. I was trading small amounts, as trading was still something new for me. I used to gamble a lot, and that too in Bitsler and Primedice. Really telling about this, giving me the nostalgic feeling. Willing to hear other people’s story on this.
Bittrex also gave a kind of first time memories with Bitcoin, because I also bought my first Bitcoin through Bittrex, Even I still have some crypto assets in Bittrex and I haven't had time to withdraw it.
There were actually many exchanges in the past that were popular, and eventually they shut down their operations permanently because the company lost money and there was also because of hacking.
But for gambling like Bitsler and Primdice I've never touched it.
I also remember some exchanges that gave me a lot of trading advantages such as Nova Exchange and Cryptopia which eventually closed due to hacking.
