I have 10k $ and maybe going to buy , but I doubt the further development of Bitcoin and I'm afraid to lose money! Can you convince me or dissuaded from buying?
Are you willing to invest all your eggs in a single basket? I think it is a risky decision, friend, and any prudent investor would prefer to diversify his portfolio in order to reduce risks.
You also need to take into account that this type of intangible assets based on changing technologies always involves great risks, because we all know that technologies are rapidly changing all the time, and even the greatest ideas can become obsolete quickly.
Putting all your eggs in 1 basket is the most stupid thing you can do. Remember there is still a change the bitcoin project fails.
So yes if you believe in bitcoin it may be wise to invest money in it but invest with care.
