I don't think that other Cryptocurrencies will take over the place of bitcoin and it is surely does have a competition, it still be the number 1 Cryptocurrency and it will never be the same with some alt coin that already failed in the market like what you have said bitcoin will remain the only solid coin that can survive for the longest time.
I think the same.
Altcoin to me is just a way to multiply my bitcoins, sometimes all my bitcoins are invested in a few altcoins but in the end i sell all of them for more bitcoins.
yeah, it is an easy way to make some good money if you are trading altcoins daily, in my opinion such trading might even make me rich in the future
yeah dude it could be possible to make a good money from alt coin trading and you it might even make you rich someday in the future I guess so

well let's hope.
