I am in the same boat as you are and IIRC got into the game at the same time as you did.
Don't sweat it for a second and continue accumulating. I know you are sitting on a pretty stash right now and I'd kill for this amount of BTC.
If there is one thing I have to thank the block size debate for is that I barely watch charts or the price anymore. I could care less if we drop to 100$ tomorrow.
Bitcoin is the only prospect left on this side of the earth for monetary sovereignty and unless you are going to drop dead in the next 5 years you are going to need it as we venture into what's likely to be a very turbulent next decade or two. .
I suggest you watch this excellent interview for a fresh perspective on where we are at. https://www.youtube.com/watch?v=uHXfEJD6DUk
Yes, it feels pretty good to have a decent stash of BTC, even though they are currently in the red....
I watched the youtube video, and I would suggest that Trace is a very smart guy, but he doesn't really come off as being very objective... and like he seems to be pushing an agenda that is so much money driven that sometimes he seems to be losing some necessary compassion for non-monetary considerations and some times the necessity for collaboration and consensus,... even if some of those practices may NOT always be the most efficient way to go.
Non-monetary considerations are the reason hundreds of millions of dollars are being wasted as we speak chasing pipe-dreams of mainstream retail adoption.
What he advocates is a return to the basics. An introspection into what makes Bitcoin great in the first place and how far we have come into picking the low-hanging fruits that will drive real adoption and growth as an economy.
People tend to forget that this is what Bitcoin is: an economy, and an economy is not built on BTC grocery bags, fancy "killer apps" and "science projects", it is built on capital investment. I remember a talk from him back in early 2014 about how Bitcoin is a storage tank, others often use the term a battery, for capital to pour in from other markets worldwide looking to be stored in & benefit from Bitcoin's unique monetary properties. Some people have seemingly lost track of these properties and are attempting to turn Bitcoin into a payment processing business in which it has no chance of competing with the existing industry incumbents.
We'd all love for Bitcoin to be ubiquitous as a currency but until a majority of people get paid in BTC and hold a considerable amount of their wealth in it these promises can not be realized. For very understandable economic reasons fiat will continue to remain the dominant transactional currency for years to come. Gresham's law will make sure of that and if we are to sell Bitcoin to potential adopters it should be on its merits as a deflationary store-of-value. Leave all that commercial consumerism to inflationary fiat currencies.
"Fiat runs, Bitcoin rests."
