I am looking for datasets of trade history, which contains the following information: date-time, buy/sell, price. The currency pair and exchange is not important.
You might want to try my website cryptodatasets.com It has free raw data and sampled data from Bitfinex and HitBtc (currently).
I found a website called CryptoDataDownload, but I'm not certain if it's precisely what you're searching for. But still, check it. Probably you can find some useful info for yourself.
