dont go full PoS, its a very bad idea for UTC and kill this coin.  Keep it mixed PoW/PoS, but reduce the min age for PoS, would be much better improvement.
Full PoS is already falling out of favor as a buzzword to pump on,  if devs care about the coin it deserves better then the cheap pump price treatment of a widely misunderstood feature like Full PoS.

If not planned and properly set up in advance by users and dev team, UTC will go from being a fast coin to move funds with with to a really slow coin when there are no users with UTC in wallets to mine PoS blocks for you, and as alot are concerned about price it can be assumed most them are keeping their UTC on exchanges and not in wallets so they are not supporting the coin at all.  

Exchanges can not be depended on to support the blockchain as they will sweep their coins to one address/not keep them in deposit addresses long enough for any PoS to occur.  
Majority of users are interested in PoS for the interest and tend to make large single stakes in the wallet, so they can not be depended on to support blockchain.  There needs to be dedicated PoS miners/nodes created well in advance.

Without dedicated PoS miners/nodes, transaction times will be very slow, hours or even days without PoW. this affects multipool as well, as it will be dependent on PoS to carry its payouts to the multipool miners.  

Does dev team really believe there are enough people keeping UTC in wallets to support transactions or maintain a fast network?  The only people wanting full PoS it seems are those who do not understand what is it and/or are only care about price.  Stable price is better then pump and dumps for a coin that is promoted for arbitrage and fast transfers of value.

The price will not go up just because a coin becomes 100% PoS, but it will quite likely crash when people find their transactions are stuck or is no longer as fast as they are use to.
