waiting is not a right thing according to me it is a potential coin and it is next to bitcoin and it has already touched 1500$ mark so this is the time to buy
i think yes because the fiat currency is dominated by a very little percentage of people who control the world economy so here is the chance to invest in bitcoin and lead a good life
yes you can invest in ripple but ripple is a centralised coin which changes the whole definition why cryptocurrency come into the market if you want to invest in a centralised coin you can do that.
yes, I think buying and holding the best way you can do trading and mining also mining is not a profitable according to me because of its difficulty rate trading is an option for you if you want to do it.
hold bitcoin the price of bitcoin is rising now it is better to hold don't make a mistake by selling it hold it as long as you can it will give you huge profit
normally when bitcoin drops and altcoin drop too but since last few weeks there has been inclined to altcoins drop which worries some people but its ok it will go up soon
