Is it impossible for the old coins to be converted to BSM automatically?
Which old coin did you imply, jiang2897?
Could you explain more about your old coin, please.
I guess you implied about Bitsum coins in old version of telegram bot wallet.
If it is what you meant, the answer is you lost your last chance to swap your coins because Bitsum team have gave miners several 'last' chance to swap their coins. I don't think that they will re-open old telegram bot wallet for re-swapping again. Which sort of action will lead to future chaotic situation that they will never want to experience.
In the past, the code of this coin was called sum. Now it is renamed BSM.
Can the former SUM be converted to BSM automatically?
