I use Google translator, I do not understand what you are writing, you are saying that it would be cheaper to sell the buildings but then you get the coins and they have a lot of level, calculating
to update and not expire is charging me 529200 gems that today is 75600 coins, I do not know how much it cost me to reach level 10 that mine, I bought the most expensive, this is the first to expire,
It is obvious that if the gems were 20 or more per coin it would be better to put together, but now that it is at that price the gems may be different, I do not know how it will be in 1 month when it expires, and what price will be the gems, but if continue as you say it is better to sell the building, but then it will no longer be profitable to have buildings
that you will sell your building, it would be good if you put your strategy, I was only collecting gems but if they go up in price then as you say it is better to sell the building
in marketplace had not entered in a long time, because it would be cheaper to get coins in gem mode, but now with the current price of gems I see that they are selling cheaper, for example 100000 gems this 14000 coins approximately current price, but they are selling it in 9000 coins, because so cheap I do not understand, thanks I had not seen, now I do not know if I buy and my building does not expire or not
I didn't say that. I said that the rebuilding cost is set to a value in gems that is equal to your purchase price multiplied by 9. For example, a base HQ costs 25,000 coins to purchase and you can rebuild it at the cost of 225,000 gems. This means that whatever you pay gems cheaper than 9 gems per coin will make you a profit when rebuilding. You can either earn at that rate (if the site let's you) or purchase in the market, no difference
something that I do not understand if I do not update a level and it expires what happens with the other levels, they will continue to put coins to me or no longer,
Other levels will stay active as each level expires individually. Expired levels will not produce hourly coins but, assumed you keep your efficiency, their MP will be counted for the purpose of sharing the mining pool
