I might be interested in posting a summary video on a personal website or something like that, however for YouTube I am aiming for my videos to be 10+ minutes. I want to give people quality information. However ( I think you would like this feature ) I will be posting a document/powerpoint of the content I talk about in the video in the description. That way if you want to re look at my information you don't have to re watch a 10+ minute video. This is give people a option to download all my content and keep in a folder on their computer for easy use.

I am offering development of cryptocurrencies, like

- create a Bitcoin-like currency
- create a Ethereum-like currency
- setup a multipool

and many others

Inexpensive development services, send private message for details.

I didn't think about buy a second.  Do others support this suggestion?  I bought a Nano S fwiw.

oh, i just think to invest in confideal.. I read a lot of good comments about it. "ethereum killer"? Why?

My friend is investing in Confideal. i know that it promotes transparency, making essential business tools available without legal or coding skills. why not

From what I heard btc gold sounds kind of shady to me(pre-mine, lack of information).
If it works and it is worth a significant amount of money then I'm afraid people will start doing hard forks for no reason and that the btc community will just support them and put pressure on exchanges to accept these new coins.

Some states are accepting bitcoin even in exchange for their citizenship.

Anyway, generally, everything that can increase country's payment balance (lessen the debt) or GDP improves the economy.
Bitcoin itself can really help countries with underdeveloped financial sphere — no reliable banking sector, volatile national currency, etc. Also, it can become a new globalization way for countries under sanctions like Cuba or Iran.
