The risk is increase in case of such coins but so is the reward. Choose after proper research and diversify.

Other coins can replace bitcoins but it is going to take a lot of time. If we talk only about returns, some coins already give better returns.

You keep counting these zeroes while I and others make real money ? Now tell who is foolish.

That is too optimistic. I have nothing against NEO but it cannot replace bitcoins in next 50 years, leave aside 2019.

I do not agree to this. In my opinion, amount of money invested is also very much important especially at current price levels.

Manipulation is possible in crypto. But I think that it is least in case of bitcoins, most of the bitcoins is with early adopters only.

You should buy at each dip starting with the first one. This will help you to miss any investment opportunity.

It can certainly help some businesses like online stores. Most of those users are already using crypto as they buy online and thus it will boost revenue of such websites.

No one can say if bitcoin will even survive after 10 years. My advise is that keep taking out profits at regular intervals to be safe.
