Nice to see some progress in colored coins development.

I've tried Coinprism wallet recently and it seems to work fine for me. But I noticed that there is very few people using current Open Assets protocol. Why?

Most people trade shitcoins or some strange tokens on various alt-chain like NXT, counterparty, bitShares and  MaidSafeCoin.
What's MaidSafeCoin anyway? Why should I trust some pre-mined alt-chains for asset management?

Sorry for these stupid questions, but I think that the solution for trust-less asset depository must be based on current Bitcoin blockchain, if we want to keep it safe.
What am I missing here? Is something wrong with current Open Assets Standard?
Will COLU protocol be compatible with current Coinprism wallet?
