Great project have a good team and so many good concept and i think this project will be succesfully at the future..

my opinion is localbitcoins and cex.io

The satoshi represents one hundred millionth of a bitcoin.

I prefer paper wallet. can store coins for a long time. next is hardware wallets. (Nano Ledger s, Trezor ) after software wallets (Exodus,jaxx ..)

Yes sure actually I am really doing it, spending 50$ month buying bitcoin for saving purposes. when my daughter will be 18 years old  she sure Will be rich 

i think bitcoin price is higher, maybe short term price is reduce,but  long term will not reduce. because bitcoin is not subject to inflation. then peoples holding bitcoins.

Coins which are in wallets for which private keys are not known, will be permanently lost. 

My Opinion is that crypto currencies are the future. many experts seem to agree, however, that crypto currencies in very big deal.

Bitcoin day by day bitcoin popularity is increasing or demand increasing, but supply is reduce.

I store paper wallet and small amount kept on exchange websites.

Fees are High Because Transaction Capacity Has Become an Artificially Scarce Resource.
