Trying to withdraw all SJCX

[something]

Yeah it’s a bug in Counterwallet. You can use any other wallet, for examples see some alternatives here:

MAX amount -> Insufficient BTC at address

It won’t be solved quickly as in within a week. It may be solved this month, but first someone needs to debug it and then fix it, plus some testing period. Last weekend I used RarePepeWallet with my Counterwallet pass phrase, and I was able to send BTC from it (it uses a different approach to compose transactions). The reason for Counterwallet having issues with the address may be that it had many unspent outputs (> 100). I see your address has 16 (http://redeem.bitwatch.co) so that may be why…
