NEM (XEM) Official Thread - 100% New Code - Easy To Use APIs

[samysamy1]

Some bright guy just dumped at a loss all the way down to 64.

Better to sell at 64 sats than 4 sats. Where are we at with development? I feel like we are losing development team steam.

Why don't you join Nem on telegram and meet some key members and make a positive contribution? Because they hardly show themeselves on bitcointalk doesn't mean that they aren't doing anything?

Sorry for this basic question: Is making a wallet backup necessary or is it enough to save only your private key and password?

saving the private key alone is a back up in and of itself. you only need to save the wallet password if you are backing up/saving the wallet file. but you should probably make multiple back ups. but to specifically answer your question, no its not neccesary, probly just best/better practice. i have two back ups of private keys and 2 back ups of wallet files. better safe than sorry

Besides backing up/saving the wallet file(.adb & .wlt), should I have to back up private keys, too?
Wallet file is not enough?
I backed up/saved  file, but did not even open a private keys.
Because private key has not password, I think it very dangerous to pick it out from account and store it somewhere.
Even if somebody took my wallet file, it is useless to him, because password is only in my memory.
But somebody took my private key, he can take my coins without password.
Am I doing wrong now?

no your doing everything fine. backing up just the wallet file is OK but to be EXTRA safe, you could disconnect your computer from the internet when you are in your wallet, and just write down the private key of the account(s) that have funds in them, and put that piece of paper away somewhere safe. (if you suspect you might have a key logger, dont do this). all electronics can, and will mostly likely at some point in time fail.. so you should keep a non-digital copy of your private key somewhere. the more digital copies you have, obviously the less likely it will be that they all fail/get lost/stolen, but its probably still best to keep an offline copy of your private key and store it somewhere you are completely sure it is safe.

Now, fully understood. Thanks a lot!
When I buy new PC, disconnected from the internet, pick out private key, and then...
memorize it!

I like backing up my wallet in a couple of places in case my computer fails, but I also have my private keys printed on paper and stored in two places that can't really be found by anybody but me.

You can also boot from an Ubuntu CD or USB and run this nice little paper wallet program.  Booting from an Ubuntu USB or CD might even be safer as it is open-source Linux.  https://forum.ournem.com/general-discussion/so-wow!-beautiful-paper-wallets!/

[yshin365new]

"memorize it!" was a joke.  
I will cut the private key written paper into 2 pieces, and store them in another places.

Price isn't everything at this point, but it's going up, and will continue to go up. I've been right so far, but this is an easy one to see. IMHO of course.

At launch the price was over 100. It went down all the way to around 55 a  week later. It went up o 72 on April 27. Today it's close  to 68, so what exactly are you are right about? This isn't much difference

After the initial dip the line is going up. This is what I meant by "overall". That is what I'm saying. Its going up, and will continue to go up OVERALL IMHO.

There may be quick peaks or quick dips, but I BELIEVE that we will see steady progress upward.

The NEM devs are not flashy and pumping NEM, they are quietly working and making improvements. This is why I think we will see slow, but steady gains. The gains are solid and not based on artificial pumps.

This is why I am big on NEM. This is not an attack on Nxt, the coin you are obviously big on. I personally like them both.

[tyz]

Much depends on the whitepaper which is coming around soon. If it holds what it promises than we will see upgoing trend.

Makoto mentioned that Nem will be having something that Ethereum won't have but it's currently a secret.

I like both and have invested in both, price dropped because people panic sold after launch, in turn creating a dump, but it was not as hard a dump as i expected, price is stable and climbing back to a good solid level.

I too dont like it when devs try and pump up their coin, or where announcements of new features are needed to pump the price, im after solid devs with solid work behind them, and thats why im happy to be part of NEM.

Finally got my stake and now I'm trying to harvest. Do I have to leave the browser NEM client open or does it harvest if I just have it in the system tray?

[NoirSuccubus]

I wasn't familiar with muut until checking out Nem's page recently. After messing around on it for a few minutes I've decided I like it. It feels neat and organized, "clean". I could see most of Nem's activity migrating there.

Can someone make a xem version of this?

When you upgrade how do you keep the blockchain from the previous install, so you don't have to resync again, is that possible?

Where is he actual NEM blockchain in the windows file system?

Upgrading doesn't change the blockchain at all.

The blockchain database file is stored at
C:\Users\Yourname\nem\nis\data (nis5_mainnet.h2)

The best idea is to start your own node and use "delegated harvesting". It's very simple!

Not everyone is tech-savvy 

[kelsey]

so what kind of coinage do you need to properly stake (yes i've read up but there are some contradiction, eg my client says 1000, but a tutoral says 10000 etc etc etc)?

any advantage in more coinage?

prior to staking any advantage or need in keeping the client running?

[tyz]

Why don't you ask the webmaster (TwinWinNerD) of the site to create a NEM version? As far as I know, he has posted here on NEM thread. Probably he is already invested into NEM.
