Glad to see this is still alive and kicking!
One question though: Is eBTC still going to be an ERC20 token?
eBitcoin the ERC20 token isn't going anywhere and isn't being abandoned, if thats what you are asking. FYI eBTC is technically ahead of many other ERC20 tokens with its batchtransfer capability which makes it possible to send up to 255 transactions in a single one with a fraction of its transactioncosts. here you can see the eBitcoin Batch-Transfer in action:
