How much Disposable Income should I Invest in Bitcoin Buying?

[Doubledoh]

I am basically brand new to Bitcoin (well, I have about 2.1 Bitcoins from a few years back), but I only recently took notice again and I just bought another ONE (so I have about 3.1 total). I don't mine, not seriously (I only allow my Gaming rig to cycle when I'm sleeping)...but I do think Bitcoin has a promising future as a currency (maybe THE currency?). I don't expect to logarithmically grow my money like I would have if I bought in 2009...and in fact, I don't really expect to use Bitcoin as a vehicle for increasing the value of my fiat holdings...

So really, I just want to buy bitcoins...for the sake of owning bitcoins. My questions are these: Should I keep buying them on the regular at these "high" prices ($800-1000+ USD as of Jan 12, 2014)? Should I invest a % toward other cryptocurrencies (and if so, which ones?)...should I buy some actual gold...or should I just keep investing all my $ into my other growing businesses in the "real" world?

If bitcoin buying is worthwhile, how much of my disposable income should I use for the acquisition of bitcoins? By disposable, I mean after all my bills and liabilities are paid...what percentage of my spending cash should I transfer to bitcoins? Should I go all in? Is there much or any risk of bitcoin simply not being valuable to humans anymore? Or is it a fairly safe assumption that they will be here for the long haul...and won't become intrinsically worthless somewhere down the line?

Thanks!

You should only invest what you can afford to lose. Remember, BItcoin may not keep rising, and it may crash and steady at a lower price. Any guesses on the price are pure speculation really.

Good topic. Wondering the same things.

Just in bitcoin or other cryptocurrencies as well you're asking? It makes sense to diversify, there are other alternatives in the cryptos world. As for alternatives in the real world right now, I don't see many. But don't invest all in cryptos, that'd be stupid too.
