I don't think XRP will become a popular currency. The smartest thing to do right now is probably investing in bitcoins, wait a few months or maybe a year.
And your money will for sure go x2.

Im using blockchain nearly everyone i know who are have a lot of bitcoins are using blockchain so im using it also. Blockchain has now already supported eth to your wallet so you can now buy eth and btc at the same time. This wallet is better than other wallets in my opinion, because its also safe and has many users using it this wallet.

If i want money. I should just sell all my coins then i would have some money i would then invest in bitcoin in order to make more money.

I think that bitcoin will rise very high so i would invest and then sell them again.

I agree on the most part. Bitcoin will rise very high. I think it will surpass 50 thousand dollars it will go to 15k first but i think that it will go quickly to 50k. So Im now saving every coin i have in order to sell it and to be rich.

I will then invest again and again in order to make more money.

Why would you teach kids about bitcoin. They will probably get involved with bitcoin in their future and will experience bitcoin themselves.
they won't understand what bitcoin is right now anyway.

I myself don´t have a job and only invest in bitcoin right now. But i think the smartest thing to do is to invest in bitcoin and have like a parttime job or something to ensure for yourself that you earn some money.

1. You can't get robbed from your Bitcoin
2. You can lose money by dropping it accidentally
3. Bitcoin is safer
4. Bitcoin can't rip like paper money
