It appears that a fundamental change for Coino coin is needed, i.e.,
A new Coino coin should be created ( with best choice of algo, probable POW(X11)+POS, long block time (333 or 365 seconds) but higher block rewards (33 or 8 from 4 Coinos/block) to cut Blockchain file size, with all balances ported to the new coin.)
In effect, A new coin (already fully mined) will be forked to and start to run energetically with new algo and any development could happen without problems.
Since the fork one month ago, problems started to show up.
The lifeline webwallet stopped working. The litesight node crashed and cannot be restarted.
A node was made by the most experienced node maker. This node started to have problems in running. New nodes cannot be started.
This is due to too extremely unprecedented blockchain file size of 1.2 GB for wallet client to take care of. The Bitocoin (with block time "20x" of 500 seconds, 9 years vs 3+ years of lifespan) has about only 1/3 blockchain size and it is not facing this problem yet.
In short, I have to give up the webwallet. Then we are free to start the coin in whatever best possible ways we would want. Because of being a new coin, we should put aside the facts that this coin used to be Scrypt-algo and opt for best choice of POWx11+POS due to being the best choice. A pure POS only new coin is more expensive to build and harder to manage.
