I think you were playing it right
provided you maintain the bet sizes somewhat so that your ROR shrinks as you grow the bank. If someone plays aggresively to a small bank and keeps progressively growing bet sizes as they win then they never escape the high risk of ruin and eventually get wiped out by a rather short downstreak. If you are bet sizing to 10 renewable mini-banks, for example, wait until your funds are actually bigger than this before you upsize. Only the original mini-bank size is actually renewable. After you increase it 5X you are no longer playing to an easily renewable amount. The bigger the bank becomes and the less easily you can replace it from outside sources the more conservative you should become.
