I can imagine that bitcoin is very strong it has a lot of funds in it and there are a lot of people investing in it too.
The foundation has been build if you asking me and it will only continue to grow stronger throughout the years.
I think the strength of bitcoin does not depend on the total funds of bitcoin, but from the users themselves. if bitcoin has little bitcoin users would be very weak and may be easily killed. but when bitcoin have hundreds of millions of users bitcoin would be very strong
I think that also it depends on the users of bitcoin, continuous increasing the users demand it will also increasing its value and in the crypto world no doubt that bitcoin if the leading and stronger coin than all other coins.
