Hello guys. I've another newbie question.

One of my friends told me about the bitcoin mobile wallet from Google Play and I couldn't understand how can a mobile phone can handle the big size of blockchain history. I read some and it says it only uses long blockchains.

I'm a bit confused. What are the disadvantages of having a mobile wallet? What can go wrong?

Thanks for your replies in advance.

Oh, I've just realised that I'm already using HD wallet. I didn't do anything special; just using the latest version. Thanks a lot.

Sorry for my newbie questions and misunderstandings.

So, in order to get another 100 slots, should I uncrypt wallet and then encrypt again and then take a backup?

Thanks for your reply.
What I tried to mean is having a new backup creates me an extra 100 slots or not?

Hello everyone. This is my first post.

I read several topics about this but I try to understand with a specific example to understand this 100 slots for wallet.dat:

Let's says I used 50 slots of my wallet and took a backup to a flash disc. Then I used 70 more slots but then lost my wallet. Let's say I restored my wallet from flash disc. In this case I used 120 slots but used backup of 50 slots.

In this case will I lose any coins?
