"Each node in Hashgraph can disseminate sealed information (called events) about transactions created and transactions received from others, to other nodes chosen at random, these nodes will add the received events with the information received from other nodes in a new event, and then They will send to other nodes chosen at random, this process continues until all the nodes know the information created or received at the beginning, and the new information can reach each node of the network in a very fast way.

Fast: 250,000 transactions per second. (7 transactions / second in BItcoin)
More just: Better mathematical configuration (with 2/3 of the network the transaction is validated). For example, a miner could NOT decide which transaction to "make" before due to the higher fee payment.
More secure: It is asynchronous. Nobody can avoid reaching a consensus or trying to interrupt one that has already been reached.
Efficient: No new block can become obsolete.
Less storage: Allows if an event occurs, everyone knows it in minutes, and only the transaction is saved, everything else goes straight to the trash.
Less electricity costs: As they do not rely on PoW (work proof), there are no miners nor would that amount of electricity be consumed. "

This is a bit of the information I found about it.

First you must get a portfolio of cryptocurrencies and then continue with the other steps prior to buying cryptocurrencies. Join an exchange later. Now that you already have a portfolio, you still have to join an exchange because that is where you are going to make your transactions. There are many exchanges, such as Coinbase, HitBTC, Bitfinex, Bittrex, BitstamP, etc.

If you talk to me about japan I can only think about dbz lol

Taking advantage of your ability to visualize or imagine can be a very useful tool to be more positive. Many of the most successful minds of our time, including Oprah Winfrey, Tiger Woods and Arnold Schwatzenegger have been known to use the power of visualization to bring that desire to their lives. You always have to be mentally aware that we are capable of reaching goals

I think any Japanese movie is excellent in the horror plot, for example "the shutter"
