I am buying though because I like to invest my fiat into bitcoin and make it into more fiat eventually.
With long term investing I am hoping to achieve this as a result that in a few years I have a lot of profit.
Bitcoin is really meant for long term investment so it's reasonable to expect that we can have a better result in the future or even now as long as we continue to accumulate bitcoin by any means.
Buying is a must but if people can't afford it then there are other ways to get bitcoin.
Being optimistic is fine as long as we have basis to do that. It's useless to have such good optimitism if we can't see some good future about a certain thing.
In bitcoin we are sure with the benefits. Im not optimistic but rather I strongly believe since we have lots of factors we can look as good basis to believe in.
