I'm going to give some tips, for that coin, an idea of mine.
1- Each game should have a currency difficulty, the most difficult type games the pyramid reward easier than the Flying.
2 - In the game flying should put 2 things, a solution would be every 100 Score a coin ai did not give a lot of money, or else put a competition who makes the highest Score within 5 or 10 minutes wins an amount.
3 - You win a lot of money and great, but there are people who do not accept wins a lot or bull up the game or the currency, earning% on top of that, So I advise you to put lower reward then you will have no problem.
4 - minimum score to get code is 600, every day +100 or one week +200

I think that's too high, some games are quite difficult like silvercell, it takes me so much time to score 100 and above on that game. Why not just 500? And it can increase +100 every week.
Yes, I agree with you, but you can not put such a high difficulty for a sinples game and a new altcoin right. they need a user. could put every 1000 Scrore 2 coin
These are all really great ideas on how to give OUT coins... But we need gameplay that takes them back too...
Maybe each game costs 1 Placo to play with potential earnings the larger you bet? Slot machine that requires Placo to play?
Each player given 5-10k coins that are sealed within the game and cannot be cashed out unless they are used 5-10x through the game?
This is how casino's make HUGE money giving away free money... They won't allow you to use it as cash, but you CAN turn it into cash by putting it into a slot machine, which in turn, usually takes the money back plus more out of your pocket.
THESE are things that will make the value of Placo rise... Right now all you have going on are players playing, then dumping their free coins on the market and hurting those who actually pay to support your startup.
Just my 2 cents

But I think it's VERY necessary to get a setup that doesn't only give coins away.
Your idea is good, but if you do not think that if it is put game of bet type of game of the dad, you have 80% of chanse only of loses and 20% of win, for the min will be only profit for the money and the owner, for nois Currency user Would not be profit.
You need to have games where the player can win and at the same time do not harm the coin.
