@adamskrodzki Dear Adam, thanks for attention. Situation: We have standard official Ethereum Wallet on desktop Linux. We have launched tokens, no problem with tokens, transfers goes O.K.. Where is problem: Every day 6GB is added to our GETH, so even big SSD are full after few days. Wallet is never capable to synchronize on classic rotary HDD, so is need use a SSD. After SSD is full there we conduct backup and erase SSD and start new synchronization. After synchronization is done, only account with ETH money is saved, admin account for control of tokens everytime is vanishing. Pure horror. Ethereum foundation with 30 million USD on account is not capable to dispatch one man into support of this issue. Note: Few hundreds ICOs use Ethereum token as standard, so we are curious, how way they conduct their business.
Shortly: How way to backup admin account for issued Tokens ?
@lnairdavis Yes, we are capable and have praxis. Please contact us on mail:
