There were quite a few folks that I began to recommend buying in the upper $300s - and I looked like a fool for about a year, then bitcoin fate seemed to have turned, and now $300s seems like a real bargain, too.
I recommended people refinance their house and take a loan to buy bitcoins when the price was $325.
The typical response was "I wouldn't go that far, buy but don't invest more than you can afford to looose.".
It is usually not good to leverage with a really volatile and uncertain asset, but it can really can pay off if you leverage correctly or if you figure out systematic ways to leverage that protect yourself from the potential downside.
I recall the various posts from you about selling your house and using the proceeds, and it sounded risky at the time - and pretty much went up after that (except you did suffer a bit of the bitfinex dip bullshit that recovered, of course).
I have a kind of 401k, and in late 2014, I was considering cashing out a portion of that 401k - yet in the end, I concluded that I had already invested enough into bitcoin, and I had no real need to be greedy about the whole matter and to overexpose myself in one asset class (namely bitcoin). So yeah of course I could have been richer, but I don't really care because I am comfortable with myself and the largely non-leveraging strategy that I employed.
I will admit that since about late 2014, I have been rotate floating various 0% promotional credit cards for cash floats, and this has been a bit risky and a kind of leveraging that I have been able to employ pretty well - and maybe with some luck too.
But, overall, I guess my point is that I do not recommend too much overinvesting, but I also recall with you that you were prepared for the downside, too with those house proceeds that you used... and so surely each of us needs to figure out a kind of balance (and not too much gambling) that attempts to not over invest or to overplay our position in one asset class.
