This is how you invest on the long-term. Two weeks because crypto has a very high trend-change frequency or “volatility”.
Every month, you invest the same exact amount of money -- whether it's $25, $100 or $500 -- in the same investment instrument. Let's use stocks as an example. Every month you buy $100 of Microsoft stock. When the price of Microsoft stock is down, that $100 will buy you more shares. When the stock price is up, the same $100 will buy you less shares. The result, over time, is that you end up buying Microsoft stock at an average price per share.
I think there will always be hobbists to keep XPM networks alive by finding some “my own chains.” Running sha256 or scrypt is totally boring by itself, on the other hand.
