clearly you didn’t read/see the responses on your last topic where you asked the exact same question. tldr 2 forms of currancy in mebc – coins which you get in 2 ways from clearing levels that go straight to your account as soon as you finish and an amount based on your position locally, you also get points which you only collect once a day at the end of that days training which increase your frame level which then changes into coins. for the shop it was changed to be always open about 6 months ago but the discounted hat still changes at the end of each season.
here is a copy paste of what i said on your last topic
for each level of mebc you clear you get a specific amount of coins:
levels 1-2 gives 1 coin each (total 2)
3 +4 2 coins each (total 6)
5+6 3 coins each (total 12)
7+8 4 coins each (total 20)
and so on
you also get some extra coins depending on where you came locally:
1st 50 coins
2nd 30
3rd 20
4th 15
5th 10
6th-10th 5
11th – 20th 3
and so on
both of these coins are coins that are spent in the shop
you can also get points depending where you finished in the global league
these points go towards your frame level which at the end of the season will get turned into a certain amount of coins depending on what frame level you are on (see here for each frames amount https://www.angrybirdsnest.com/forums/topic/coin-average-from-each-mebc-frame/)
throughout the day you will obviously get lower and lower in the local and global tables as more player play and get higher scores than you so you might start the day in 8th locally with 5 coins and 1000 ish globally with 70 points but by the end of the day you might be 20th locally with 3 coins and 3000 ish 53 points
as for the shop it is now always open with the discounted hat changing at the end of the season when your frame gets changed into coins but you can still spend the coins you get from each level and your local position whenever you want.
finally if you want to get high in the tables you now need to finish both daily challenge and king pig challenge as both of these gives an extra bird for mebc (daily gives you the bird of that day – Monday red, Tuesday blues , Wednesday, chuck, Thursday matilda, Friday silver, Saturday bomb, Sunday terrance. king pig gives you one of the 4 extra birds – hal, stella, bubbles or leonard)
