To the devs of AE:
My main focus is on BOScoin, which was a competitor to the time of the AE ICO.
But still i didn't loose my interest in AE and purchased "some" recently after you announced the TestNet, because I believe we need more and differenet blockchain platforms and I like the improvements of AE over ETH.
I'm pretty sure the value of AE will rise quickly into 2 digit no. the closer MainNet launch gets.
Now: From my experience with BOScoin I'd like to draw your attention to a problem with exchanges you'll run into with the new AE token API at MainNet, leaving ERC-20 standard.
(BOScoin isn't ERC-20 and started with its own Stellar API.)
I can predict that HitBTC will not change it!!!
Since 3 month we (BOScoiners) are waiting that HitBTC installs our API, that our coins can be desposited and withdrawn (HitBTC purchased around 700k BOScoin at ICO and sells them still as IOU at their exchange).
They just don't do it! (Btw. HitBTC charges new ICOS with ERC-20 token $400k to be listed. Got that from a CEO of a coin, who asked 2 weeks ago.)
The situation with exchanges have dramatically changed since May 2017.
Many ICOs are piling up in front of known exchanges and doing "nearly" everything to get listed.
You can dream of binance and bittrex, but IMO they will not list you or without an exorbitant and embarassing fee or some "connections".
And I don't know wether Liqui.io will change the token API ??
I heard from several ICO CEOs that they don't answer to any way they tried to contact them.
I'd suggest that you don't wait but try to get listed to some more and new exchanges, now, that might change the API quickly after MainNet, when heavy volume will be traded.
One recommendation for that would be
www.KuCoin.com at which BOScoin will be listed soon.
They are a fast growing and clever,
gathering all major blockchain platforms and pairs!
And they are eager to grow and attract more volume and you get quick responses from their Telegram channel or Twitter.
IMO KuCoin would be one of the perfect places for AE and the change to MainNet.
I'm sure they would be glad to take AE in (to their regular listing fee, which is reasonable and btw. negotiable.)
Please don't wait with that step to add more exchanges until MainNet, but do it now.
