There is information from the developers, when will the usual purse for coins?
Do you mean online wallet?
Online wallet would greatly simplify the task. I don't really want to install the software on my computer.
Perhaps over time, the developers will develop this wallet.
And for what reasons this project must need to create own wallet?
Such projects require their own wallet, as it will not be very reasonable to use someone elses wallet (like Ethereum).
Lol, why you think so? Explain please.
On the one hand, this is an advantage, on the other hand a disadvantage.
What is the main advantage? I don't quite understand.
The advantage is that if the project will use the Ethereum wallet, then more users will join the project than when the project will use its wallet.
Depends on the wallet, but yes probably more people will use it with the Ethereum wallet as there is less risk in using wallets that are known to be well working.
You have strong network effects of course if you use a wallet that is based on ETH and more people know about it and where to get it.
