Hi Dennis, and thanks for the post here! 
And, if I have understood your other thread correctly, you have been regularly adding to your holdings?
Crypto is such a strange environment for me, a basic Crypto amateur, to understand. All normal fiat currencies at least have some kind of intrinsic value based on their economies and central bank policies, and commodities have some kind of intrinsic value based in their usefulness and desirability.
But BTC has absolutely none of these attributes whatsoever!!! It is literally non-existent in any form other than as a piece of computer script (which, in theory, can always be recoded if everyone in its environment agreed to any changes) …
But it seems there are only two attributes underwriting the value of BTC: 1) its limited issue size at 21mill tokens, and 2) its attractiveness as a payment medium for illegal transactions.
The first of these is quite strange in itself since the ceiling on the number of “coins” in circulation does not limit how much can be invested in them. It starts to work like a inverse inflationary process.
When a currency weakens against, say, the USD, then see more and more zeros added to the right hand side of the units, e.g. we start with 1 “juju” = 1USD, then the juju weakens and we end up with 10,000 jujus = 1 USD.
But with BTC, it is working the other way as it strengthens and we start adding zeros to the left hand side. e.g. 0,000001BTC = 1 USD.
So we could say that the ceiling is irrelevant here since we just keep dissecting each token into ever increasingly smaller particles…
In addition to that, there are more and more “look-alike” and “not-so-look-alike” Crypto being launched all the time.
The second issue of the “grey area” usage of BTC is (hopefully) going to be progressively curtailed as all the regulatory authorities applied tighter rules at the crypto/fiat interfaces. But will this, in turn, cause a lot of BTC to be liquidated in front of these changes?
Without the decentralised/unregulated aspect of BTC, together with the unlimited availability of various crypto, and with the increasing use of crypto in normal trade/business transactions, will BTC lose its uniqueness and identity? If so, where will its value be? Anywhere between zero and the heavens above! 
But in the meantime, make hay while the sun shines! 
I did manage to catch a (small) couple of trades on the way up to and above USD100,000. I had to close out for a while as our last guests from the holiday season left for the airport. Now life is back to normal again for the coming year… well, at least until Easter!
