Some answers to questions:
TagCoin on Tagcash is the same as TagCoin on Stellar - we are also creating other anchored assets as well, namely Fiat (eg PHP, Israeli Shekels, and more), Tokenised Bitcoin, ERC20 assets, NEM assets like Loyalcoin and so on. We are also integrating directly to accept assets created on Stellar itself. This is so we can offer trading via tagcash into the Stellar decentralized exchange (DEX), and also as a payment method within Tagcash Wallet, or for remittances.
Anytime we create an asset on Stellar, we also create it on our own internal multichain blockchain for whatever use cases that is needed (transaction free movement of assets without using our APIs usually). The only assets that sit ONLY on the Tagcash Blockchain are rewards, share tokens and Non Fungible Tokens created within Tagcash. Everything else either already exists on its own public blockchain, or inside a platform (such as Ethereum ERC20, Stellar , NEM etc). We just tokenise those for easier use within our platform, or on stellar to allow easier decentralized trading, and act as the anchor bank for them.
I have removed our TagCoin batch from sale on DEX, since there seems to be a few others already selling it there..and let the market find the right price...:-). When the time is right, we will offer more for sale as needed. Hopefully the price rises, which is good for all..

. A lot of that requires more use cases in Tagcash, which we are hard at work on creating.
Later this week, we will be pushing live, the changes to send and receive stellar assets, where we have them issued on the Tagcash Wallet (including TagCoin of course), using federated addresses, and to create your own nicknames (eg: mark*tagcash.com is one of mine). This way it makes it super simple to send any asset we have "stellarized" between any Stellar wallet out there. However, some of them are not so good at recognising federated addresses, so anyone finding this, send the creators of those wallets a message to correct it.:-)
As for Stellar Term not recognising TAG, that's an internal thing in the their app, and we have to get 100 Reddit Karma points to ask them to change this..not entirely our problem, but it would be nice to have TAG and PHP on their wallet with the graphics, so you don't have to put the issuer address for it..

Just in case you need it, the issuer address for Tagcoin is:
TAG
