There is no doubt that bitcoin is a coin that many people invest and it has been proven that bitcoin will provide great returns in the future. Maybe the price of bitcoin has fallen deeply but the price of bitcoin will increase again in the future. Now is a good time to invest in bitcoin because with the price going down, we can buy lots of bitcoins and keep them until the price goes up again.
But not everyone has the money to invest on bitcoin since even when it's crashed quite hard, it is still considered very expensive for most people. But yeah, it is a very solid coin to invest if you have the money and knows when to enter the market. Right now market condition seems recovering a bit from the recent crash. After a few days worth of crash, we're finally seeing green(s) on most major coins and alts. So I guess, to those that have patiently waiting for this time and already stuffed their portofolios before, right now they are just enjoying their profit, tho some might be also still suffer from losses.
