Furthermore, initially, I had been thinking that if I get into this thing (bitcoin), what are my liquidation possibilities and potential exit strategies.
I don't think in terms of liquidation or exit. In my planning, I have built a number of laddered 'diversification points', none of which, itself, divests a large percentage of my stash. Risto codified this as his 'SSS' strategy, though the concept is obvious in and of itself. The basics being 'every time BTC value increases by N*, sell M%', where N and M are constants of your choosing. In my case, each diversification point is enough to make a significant upgrade in lifestyle, without depleting principal.
Either this thing goes where there is no reason to exit, or it crashes to nothing. For me, there is no in between.
Actually, I am on the same page as you too, regarding the mostly accumulating and holding, and strategically and intermittently cashing out as the price is likely to increase.
I read the SSS plan, and I have created my own variation of that involving both cashing out and trading... the trading part I began in October 2015, and it is intended for me to continue to accumulate BTC and to bring down my average cost per BTC. In essence, as these aspects of my holdings adjust, then my modified variation of the SSS plan adapts as well in my own formulaic ways that works for me to create a plan ahead of time but to tweak it in logical ways that works for me and is not emotionally driven.. and includes a long term expectation that BTC prices are going to continue to appreciate in ways that provide larger overall returns than other assets.
Regarding my points about regulation and liquidation, I am describing dynamics that influenced my decision in the beginning about whether and how to get in, and even though there seemed to be various challenges in these liquidation and regulation regards, those challenges have largely disappeared and have become less prominent in the bitcoin space.
