Wallets are nothing but storage to store your cryptocurrencies. There are services provided by exchanges as well as core wallet providers. Looking at the security part offline wallets are most secured because they can not be hacked. These are often called as hardware wallets.
if we see the market capitalization of bitcoin (first place) and Ethereum(second place), there is a difference of $160 billion. It's a very huge gap and not sure it will be filled in the near future. So BTC will be always in a dominating position. And no doubt of its number 1 place for the coming years.
I am in the crypto market for a year and I must admit that I missed the train. Most of the projects I worked on, turned out to be a scam and remaining are running around 90% down Hoping for the best, still holding those which includes BNK, VELIC, CPT, UBEX and so on.
From my point of view, $14 price fo ripple is too high. Even though Ripple is a cryptocurrency, it's kind of with off-blockchain features. Sure, with this bull run or near future pice will increase but not touch two digits.
