Let's assume i have created a game, and then created ERC tokens (Example swords) so the player must buy a token to be able to play the game.
What if someone creates similar tokens in his wallet and injects them into my game as if they are bought from my tokens store

Since the launch of Eth 2.0 seems to be earlier, will this news drive the price of Eth 1.0 down ?

Is there any good website(s) that rewards DAI for simple tasks such as click ads or watch videos etc...?

Is there any crypto games to earn some crypto "WITHOUT" the need to spend GAS or blockchenization fees to trade NFT assets.

Is it a good idea to buy some crypto for long time investment plan from exchanges such as binance as keep it there, any alternatives ? Because i have heard bad things about some famous exchanges such coinbase.

Problem:
In the traditional "Black Market" Third Party Gaming item trading website the seller submits an item and when its sold the third party gets a commission out of the sale.
When trading gaming items on the blockchain Minting" the seller has to pay blockchain fees in order to submit that item to the blockchain, and that's quite problematic because the seller incurs fees even if the item doesn't sell. So the seller looses money even if the item doesn't sell !!!
Think of it, as if a seller pays for shipping costs on amazon even if the item doesn't sell.

Solution:
The seller offers the gaming item on a market, after the buyers decides to purchase the item it gets blockchenized and the fees are deducted.

Is there anywhere to create a FREE eso wallet without the need to make a deposit? i want the account to be able to play prospectors.io

I was wandering why most of crypto games (such as cryptokitties etc...) Adopted Ethereum blockchain rather than Bitcoin Blockchain ?

currently players are playing games for 2 reasons:

1- for real fun such as Elder scrolls online , Guild wars  , GTA etc...
2- to earn bitcoin and other cryptocurrencies which are mostly some sort of browser games or simple mobile games

Isn't there any good title that combines both, having great fun while earning cryptocurrencies

Greetings,
I would like to invite you to participate in the alpha test of a new online game which will integrate bitcoin to let players buy and sell game assets (Cards) for bitcoin

warriorcards.com

Advantages of the game:
-   Buy, sell, manage and upgrade cards by participating in battles either against a bot or other human players
-   Skill-based battle system where your management and development skills effects the outcome of the battle
-   The battle processed on the server therefore no one can manipulate it using bots or cheating software

Greetings,

Lets say i developed a web application that sends and receives bitcoin to and from users (such as online store), and then hosted that web application on a hosting service provider. how can i make sure that the hosting Owner / Manager won't compromise / steal key and password information and use it to login to my wallet and send bitcoins to his account  ? after all,  the process of (private key + public key  + ScriptPubKey etc...) is done on their server which could be seen by them!!!
