For now bitcoin is really a big thing and i guess this can be bigger after a year, many rich people invest their money to get huge profit but of course its not about always on profit ,you need to face that fact that if you invest on bitcoin there is also a chance that you can also lose your money.
The price of bitcoin is so high that the risk involved in investing now is really huge as the possibility of a crash could scare any small time investors ,one thing is certain,the price wont go higher all the time,there will be a time when there is a correction,make sure you ride the market and book your profits in time and play safe.
