The gap between venues
Cheapest on Bitget, dearest on Gate, 1.12% apart. Those are quotes, not profit: two sets of fees, the transfer and slippage all come out of it.
What this coin is
IOST is a token trading under the ticker IOST. The project is classified under "Smart Contract Platform". It runs on BNB Chain. Market capitalisation is $29.4M, ranking 664 by that measure. 36.0B are in circulation out of 36.0B. The all-time high was $0.129829, reached on January 23, 2018.
Contract address: 0xaf48b7e315a52518cfbf7d96c455d9dfad94cb48. This is the only reliable way to confirm you are buying this coin rather than a namesake: tickers are not unique in crypto.
Deposits and withdrawals
Venues open trading before transfers more often than you would expect. What they state right now:
| Venue | Chain | Deposit | Withdrawal |
|---|---|---|---|
| KuCoin | Iost | open | open |
| Bitget | Iost | open | open |
| Bitget | BNB Chain | open | open |
| Gate | Iost | open | open |
| Gate | BNB Chain | open | open |
| Gate | Ethereum | closed | closed |
| HTX | Iost | open | open |
Note that withdrawals are closed on Gate. Until they open, the coin cannot leave — that matters more than any spread.
Contract address
The same ticker routinely covers different tokens on different venues, and buying "the same coin" on the wrong chain or at the wrong address does not come back. These are the addresses by which the exchanges we collect from identify this coin:
| Chain | Address |
|---|---|
| BNB Chain | 0xaf48b7e315a52518cfbf7d96c455d9dfad94cb48 |
| Ethereum | 0xfa1a856cfa3409cfa145fa4e20eb270df3eb21ab |
Check the address before you buy and before you transfer. A matching name and ticker mean nothing: anyone can issue a token under any name, and most fakes are built on exactly that.
What to watch on a fresh listing
The first hours after a pair opens are the worst time for size. The book is thin, so an order of a few thousand dollars moves the price by itself and fills well below what the table shows. And a word on tickers: they are not unique in crypto, and the same name on two exchanges regularly means two different tokens.
