Thank you for all your answers. As usual this give me even more questions.

Have a few more.

1. If now every ERC20 token uses the same blockchain as Ethereum, this means that Ethereum can process extreme amounts of transactions? There are well over 100 ERC20 tokens, while Bitcoin can't even handle itself. Is this correct?

2. All ERC20 tokens are airdopped/not minable? I guess ERC20 tokens have there limit because of Ethereum, and are very dependable what Ethereum are doing?

3. How can i send an ERC20 token on the Eth network when they uses the same adress, how can the blockchain know if i send Eth or modum?

4. Eth and btc uses different blockchains, btc has their own blockchain and Bitcoin Cash is a sidechain of bitcoin blockchain? while ERC20 tokens uses Eths blockchain. Stratis,waves, Cardano and so on have also their own blockchain? Which means they all have seperate wallets? If this is correct it would means that every coin that doesn't uses Eth or Btc blockchain have their own wallet?

5. Have you any examples of Dapps except Cryptokitties?
