Hi @stackin
So glad you are having these contests.
I am very new the crypto world and have almost no knowledge of how to find quotes and stuff. I did a google search and found a site and was following the PRICE OF STEEM for a couple of hours before posting my guess since I have no idea how it might move.
Apparently I have been following a different quote which the STEEM price was about $.30 lower. Only minutes after the contest did I realize it was a different one. It says CRYPTO-POLONIEX CALCULATED BY TRADING VIEW.
Anyway next time I will check thoroughly.
Well that was the excuse for not winning this time. But there is more..
I also want to humbly make a couple of suggestions:

1. Since there are many participating when the contest is something like STEEM then if you have a rule saying we must have at least three decimals (Example: $2.563 instead of $2.56) then repeat predictions could be avoided.
2. Give the deadline about 24 hours from the time of posting as you do but give a WINDOW for posting say an hour or maybe two hours. So people will not get influenced by the others. I was the winner last time and was a little hesitant to post early because I might get "cut and pasted".

Thank you again for having these contests.
