Purchasers must have a user-controlled Ethereum address at the time of registration. This registered Ethereum address will be white listed for purchasing Host token in the Host token sale

No one will not be able to purchase Host token from a non-registered Ethereum address during the first 24 hours of the token sale. If any Host token has not been sold after 24 hours, the token sale will be opened up to non-whitelisted participants as well.

Purchasers will be required to go through a mandatory registration process.

Of course! Here's how we work on this:
Bandwidth: The Protocol will be able to process up to 500,000 transactions per second. This will expand the boundaries of application and will allow the use of cryptocurrencies in the banking and financial spheres.
Easy exchange all over the world : Make payments online or offline using the mobile app, as simple as you've done with Android Pay Apple Pay.
Corporate market: Secure shopping worldwide in the international Marketplace-Tkeycoin,with cashback up to 30%. Buy any goods-products,cars, real estate,pay for rent, Internet, get financial services. The list of stores is constantly expanding.
and this is just a small fraction of what we have prepared

Second thing - the absence of the corporate market: Users cryptocurrency can only sell and exchange their assets
The next one - narrow application: Cryptocurrencles are mainly used as a means of earning for investors and are practically not used by another part of society.
And to the last one - hard usage: To start using cryptocurrency, a person needs to deal with a number of technical issues
