Yes of course..Ripple is a superb coin.I think it maybe go 10$ end of this year.Ripple has a 3rd place in coin market cap list.Ripple is great investment.
Are you store some coins long term? I think safe way to use wallet. Are you trading some coins short term? you can use exchange.It's good way to trade.
Invest is Good.Because you can buy new coins on your own research and win.But you can't invest or you want more money, you can do bounty and collect more money.
I don't think so.Crypto is not end.Crypto is developing the world and change future. Not too late invest.Many new success project coming soon.You can invest new or old projects.Exactly I believe in crypto. My favorite coins are ETH,XRP,ADA,TRX,TNT and etc...
I think BTC,ETH,XRP are good to hold long term.Other Altcoin are good to hold short term.like XVG,TRX,ADA...etc But short term risky.Long term is great.We can earn big profit in long term.My recommend is long term holding.
I haven't my own house.So I hope to buy a house.And I haven't a car.I want get a car.I'm earn 1000$ in a month.So i hope to do this works.This is my plan
