great thoughts. but does this mean you don't own or trade any currencies or only the "unproven" ones?
my take at the issue is that cryptos and blockchains are essentially good and have perspective but not the hundreds (actually over a thousand) we see now - most of which are just derivative and speculative.
the thing to realise is that the market is very young and not matured yet - the oldest one (btc) has been around for only some 8 years. i.e. it still hasn't stood the test of time and the market is behaving erratically and in my opinion the air needs to clear in the coming months and years. it is an interesting look at e.g. coinmarketcap.com from 2 years ago and now - see how many currencies have since ceased existing and how many new ones emerged.
overall, however, I still see the potential in some of the basic and established ones, just can't quite tell where is the limit and when the potential will be realised (if I knew, i'd probably be a millionaire by now)
