A volatile market attracts traders and speculators. A stable market attracts merchants and businesses. Whichever fits your liking, either way the market will still grow. The question is how solid would the foundation of each option be since both markets has its strengths and weaknesses.

But since I want to have my coins be spent somewhere, I'll choose a stable market since it will attract business owners to accept bitcoin and have the economy stimulated. Growth potential is higher compared to an on-off volatile market.
