I don't think you need to be afraid if only you invest your spare money the mony you can afford to loose without causing you discomfort in any part of you financial, and family life. Bitcoin has rise above expectations in 2017 and bitcoin still has the potential to do more in this year 2018 but we should not also forget the fact that bitcoin price is always volatile and at that it can not keep going up always it will get to a point when the price will still drop down.
I agree there is no real reason to be afraid of bitcoin and as long as you only invest the money that you don't really need then there is no need to stress about it. And even then i think that there is a really small chance that you will lose some money i think you will get easy money by just being patient.
Precisely, there's nothing to be afraid of but rather to be aware on your surroundings. Bitcoin is not that bad, because it is made for online transaction such as trading and investment. Bitcoin is risky but if we didn't take the risk then there's no profit, yet the more risk the things is the more profit you'll get.
I agree to them, as long as you know what is bitcoin and it's disadvantages you don't have to be afraid of it.
You just have not to be greedy with it and just invest what you can afford to lose.
In the fact that bitcoin brings us here there us nothing to be afraid of.
