Bitcoin is and will stay very strong and will become stronger
thats true, from now on bitcoin can get only stronger and stronger though it depends on people too if there will be a lot of interest in it it will grow fasteri hope people will invest more and more money into it thus pushing the price up and making it a currency of the world
future looking bright, brighter than 1000 stars, we will be all rich, just hold onto the coins guys! 
Don't be too much greedy, don't hold your coins forever to get rich by the growing price of bitcoin, just sell them when you feel you are getting enough profit, and after selling them start collecting again and hold them again until the price goes higher and then sell them again.
Yeah that's true we need to believe in reality, the future is good but we don't know how long it will survive but it would be wiser to buy now and keep it safe for future.
It will survive for long time mate as this is just an beginning of bitcoin, we cannot arrive so fast at any decision that it will not survive, it has brightest and safer future ahead.
We just can hope that it will be more worth later but the bad thing is that you cant control it.
