Coinswap to the present token DOT and Scrypt-mining (& all the mining pools @Cryptopia) are all gone more than 5 months ago. You have to check the Forums @Cryptopia to see some info and possible updates. I do not see any reason for them to run the old blockchains and enable transfer of old DOT from old mining pool to any old wallets; Nevertheless, You can still get the private keys for your coin addresses without syncing with the old blockchain. How to get old coins swapped to new DOT is up to a ticket and contacting the support team.
