VERY IMPORTANT 


pls how to do that on my phone

1.) Search %APPDATA% if on Windows.

2.) Navigate to "local" folder.

3.) Copy and paste byteball folder. (DO NOT DELETE OR MOVE IT.)

4.) Place the byteball folder in selected backup location with the paste function.

 

where i can take testnet Bitcoins?
thanks

Two options:
1. (crazy) back up the app's data folder (e.g. on windows C:\users\<your user name>\AppData\Local\Byteball test).  You'll have to do that every time you send or receive blackbytes or any other private asset.

 
2. (practical) set up a multisig wallet with redundancy on two or more devices.  E.g. 1-of-2 on desktop+smartphone.  If one of the devices fails, you still can spend the funds from the other device.
 

Unlike Bitcoin, private key in Byteball is not enough to restore access to funds.  Hence, to avoid giving false sense of security, I removed the export function.

Transaction cost is a basic anti-spam measure, how can you remove it?

Maybe a little bit OT:
I’d was just reading that migrants sending every year 440 Milliarden Dollar home - most to Albanien, Afghanistan und Nigeria.
They use travel agencies, supermarkets and kiosk near the station to transfer the money using Western Union, Moneygram and Ria.

„Use BB.HS (BB- home-send) get 64,2 kB for free” 
„Save transfer around the world in seconds. Your BTC / Byte Dealer (every fu.. kiosk owner) will help you to tranfer.“

Yes, I know the problem ist the interface fiat<->crypto. So, maybe therefore  crypto will be a hidden layer for a very long time…
But people which selling cigarettes and lottery ticket can also sell BTC or Bytes using her mobile..
The problem ist to generate a initial demand - we have a classical problem https://en.wikipedia.org/wiki/Chicken_or_the_egg
To break the barrier and to initialize a Revolution, the fees have to be so smal against classical competitors (Western Union, Moneygram, Ria) that the people overcoming habits , fears  and prejudices.

That shoud not be a great Problem: I was reading they take up to 8% for sending 200 $.
In my opinion it’s much easier  to rush a existing market than enter a market wich will come in the future (IOTA).

@ lerecidiviste: you will receive some funds
