I've received this error :
billed CPU time (1277 us) is greater than the maximum billable CPU time for the transaction (0 us). I guess I need to stake EOS for CPU. If I stake for example, 3.0 EOS for an account, do I need to wait 72 hours to be able to complete new transactions? I just staked 3 EOS but my bandwidth was decreased from 18.95 msec to 6.8 msec.
There is how I stake:
cleos -u https://eos.greymass.com:443 system delegatebw myacount otheraccount "0.0 EOS" "1.0 EOS"
