Hi

New to trading. Observed an interesting phenomenon yesterday. While the international exchanges are trading high and low, Coinsecure was constant from yesterday night at 176500. (This has been happening often in coinsecure)

This as per my understanding was a huge sell order for 40L for about 23 bitcoins and till I am writing this post its still going on as not enough buyers from yesterday.

Was wondering what could be his motives..
1. Seller wanted to clear all BTC due to upcoming fork?
2. Due to tax, GST? (Its month end, but wait, shouldn't be buy order then?)
3. Or simply a millionaire playing with this "small amount"
4. Trader trying to bring market down, and then buy at lower prices? (why so when upcoming fork itself poses that scenario)

What should we do?
1. Buy as this is a good oppurtunity? (Price dropped from 181k to 176k sharply at 7 pm yesterday, Intl exchange very slowly raising)
2. Avoid buying and wait for price drop? (As this huge sell may bring market down to 170k for eg)

Please share your thoughts.
