I think a small smaller proportion of your wealth you should consider storing in it. As we can clearly see that bitcoin is become so volatile, as it's prices fluctuates a lot. Bitcoin from the day of origin bitcoin is growing in prices and now skyrocketting. As saving your bitcoin is also on Internet as it is a digital currency, Unfortunately, IT security is a real-world issue, not just for bitcoin but within any industry that uses technology. You only have to do a quick Google search for recent hackings of large global companies to see that any company is open to security issues regardless of size or industry. Therefore bitcoin may seems very easy way to invest and to earn but it is not that easy as it appears. It has its own risk.
Every investor will tell you to never go all in as it is good to always diversify so as to reduce the risk. There is no safe investment and we just have to understand the risk. Moreover, the more we understand the risks involved, the more we ourselves will try as much as possible to thread safely so we do not end up fumbling at the end.
Greed is not good for any business, but for anyone who feels they can go all the way, even with the risk, then that is definitely their own call which may pay them or mar them.
