Do not walk away from Bitcoin investment because you don't have the money, it's even better not to have money because you will have the patience to learn more about everything, and when the money comes, you will be able to avoid many dramas.
What could be more agonizing than being in such predicament.
I could tell you that, there are those who are buying as well as learning, that’s the better position to be, you wouldn’t always win neither is failure always your end result. You win some, you lose some. It’s the way of business and investments.
Some people out there just never see themselves to have enough funds to invest with but in the real sense, they can actually strive with what they have. More often, they never do.
Don’t be in a haste and neither should you fail yo take opportunities if you could manage it.
The belief that one never has enough to invest is often mental rather than financial. Start small, study often, and build your investment with knowledge. Choosing patience and persistence over haste often pays dividends. You correctly stated, "You win some, you lose some." The essence of investing. The tricky balance is being cautious without letting fear stop you.
