Hardware wallets are good but if you dont have them i prefer to keep in a paper wallet (dont copy on your phone or computer, just keep as a phisical copy)

It's growing slow but strong. If the pump continue from november 2017 to till now, so many ppl will think yeah bitcoin/altcoins are bubble but these slow movement makes market stronger as i see.

I think your question is not about which one is better. Eth may be better than Ripple as technology, practicality stuff like that. But you're looking to invest so you decide by their future. I think both of them can jump 2-3x easy but Ripple is more movement.

If it hits good exchange and less ppl can invest at ICO, i perefer to hodl for a while but ,f i dont have hope with it and it starts about 1.5-2x, i'll directly sell it

Actually i was objecting Ripple, coz of its not decentralized but it has a good financial source behind and has good partnerships with banks so may be xrp would be the first coin used by banks.

Nowadays IBM, Sony, Ticketmaster, Maersk Line and a lots company which i dont remember their name interest with Blockchain. Even they are not bank, they are not financial technology companies but they see a future for blockchain and started to research and development working. So even we dont need, companies will need.

It's already started to change. You dont need to carry shriveled notes in your pocket ICO is very good crowd-funding method for startups. Or at least you dont need to pay fee or wait a lot when you send money. These things are very simple for ppl who interest with crypto but even these simple things are huge change for current economic system.

But most of them include more detail which investors mostly cant understand well and very technical. Thats why i look up whitepaper and ico's website together.
