I agree. If your investing horizon is a lifetime, these little 30% fluctuations will make little difference. Sure, your gains might be a bit larger. However, it also assumes you want to sell. Why sell when you can collateralize?
You're right. Of a $50 dollar cost average buy, I only lose or gain a few dollars from daily price fluctuation. Hardly life-changing. If I had a few thousand to invest, I could see price being significant. But, at $500,000 BTC, will it have mattered that much?
