In my opinion, dApps will become popular in 2019 when a lot of ICOs completed in 2018 will launch their product. I have seen that some projects are working so hard and their products will be released soon.
Don't advice financial, but let's choose top coins/ tokens on CMC then do your own research to choose some (don't all in one). My portfolio: Bitcoin, ethereum, xlm, bnb and vet.
If anyone can know exactly, he/ she will become $billions. I think a lot of people who has bitcoin when it born but they sold out when x5, x10. In this market, nothing is impossible.
I don't store my coins/ tokens in one wallet, it's so risky. I use Mew, Imtoken, metamask or coins/ token itself wallet. I'm looking for a hardware wallet like Ledger, looks like it's also a great choose.
I don't think blockchain will beat Visa. For now, I haven't seen any projects which has changed a industry in real life but I believe that it will happen in the future and Visa can combine/ use blockchain to improve their services.
Agree that with you. Scammers operate anywhere, anytime in the world even in real life. So let's be careful to keep your money. I have seen a lot of people those who lost their money by scammer.
For me now, I stayed out of market. I'm in stablecoin and wait to buy. My portfolio is 50% for bitcoin, 30% for ETH and top altcoins, 20% for some new coins/ tokens. In my portfolio, bitcoin has been focused.
