The volume was exceptionally high on two days. One day was a major sell-off (October 10th), which is when Bittrex originally stated they would be delisting Unobtanium due to low volumes. Clearly people saw this as a weakness for the coin, and sold. Shortly after (October 20th), there was a major buy-in. FallingKnife (a rep of the Unobtanium team) claims this was one person buying in for 16,000 tokens; see original post from a week ago above.
But regardless, Bittrex removing the coin was totally within their guidelines as the coin was consistently below 5-BTC of volume / day. Link: https://ibb.co/mBvYqm
Of course this link is from Cryptopia's volume, but Bittrex volume wasn't actually much higher, tho it did break 5-BTC a number of times, Bittrex requires 5-BTC a day and consistently missing that is grounds for delisting.
Moving on... Simply people moving tokens from Bittrex to Cryptopia wouldn't raise the price or the value of Unobtanium. You need to have movement of funds, with new buyers entering while previous buyers hold; this in effect causes deflation (less supply available for trade) for the buying market and raises prices. The ways we will see an increase is by the Unobtanium team investing time/money in marketing and development. I have not personally seen any sign of this. To be totally honest, this coin seems to have some sort of community over the years, but the activity is not specifically high. The team has also shown no signs that there is much or even ANY development. This is certainly disappointing as I'm sure many people bought in at highs and are suffering substantial losses as the price widdled back down to where it started before the boom on the 20th.
