I have a few questions

1. Will this token have safety features that will prevent someone from buying up more than 51% of the supply which would give that person control of the token

2. Which exchanges take ERC20 tokens and is there any free exchanges like the Waves platform where anyone can list a token for free?

3. When you create a token with 18 decimal points does that mean that's the max amount of zeros that token will have for example 0.000000000000000000? what if the price is 0.01 will there still be 16 zeros behind that number? Sorry a little confused about this

4. What if you send a ERC20 token to an Ethereum wallet what would happen, why do I have to use Myetherwallet?

5. How exactly would I make a ERC20 crowdsale token using this service? Any video tutorials?
