June 25, 2018 is TRON's Independence Day.
It marks TRON's departure from Ethereum, as TRX, previously a ERC20 token from Ethereum, migrated to TRON, achieving absolute independence.
Token migration must be completed before June 21. By June 24, TRX ERC20 tokens will be changed to TRX tokens that can be withdrawn from exchanges. Following is a list of exchanges supporting migration.
Bi, Bibox, BIHUEX, Binance, Bitbns, Bitfinex, Bitflip, Bitforex, Bithumb, BITKOP, BitoEX, Bitpie, Bittrex, Bit-Z www, Bixin, BJEX, CEO, COBINHOOD, Cobo, CoinBene, CoinEgg, CoinEx, Coinnest, Coinoah , CoinTiger, Cryptopia www, DragonEX, Gate.io, HitBTC, HPX, Huobi, IDAX, IDCM.IO, Indodax, Koinex, Lbank, Liqui, Livecoin, lomostar, Maincoin, Max Exchange, Mercatox, Mercatox, OEX, OkCoin-kr , OKEx, OTCBTC, Rfinex, RIGHTBTC, sistemkoin, stock.exchange, Tokenomy, Upbit, Zebpay.
What if I fail to migrate my TRX tokens before June 21?
Don't worry. Just make sure not to migrate them during June 21 - 24. But note that after June 24, they will be useless unless you migrate them. Only some of the exchanges will support migration then. You'll need to try exchanging them to check, and then send your TRX ERC20 tokens for migration.
