OP, while it is generally a good idea to ask veteran players for their opinion, it is not very effective if you ask the same question or a similar one every other day while not taking the answers into account or trying new things out in the meantime. If you are desperate for a battleship, even one as trollish as Oktblabla, go ahead. If you are decent with cruisers or destroyers (neither appears to be the case, so your latest question is moot), buy a cruiser or a destroyer. There are several cheap coal ships if you are in such a hurry, but a particular selection will not serve you well if you do not really try out classes and playstyles BEFORE grabbing premium ships. Believe it or not, fresh players do not perform better in premium ships than in silver ships. In most cases I encounter, the opposite is true. Take your time and spend it following the advice you have been given.
