At the current market condition and having bull run in mind, these persons have $10,000 to invest.
- Mr. Bob goes 100% with bitcoin.
- Miss Alice goes 50% bitcoin and 50% random altcoins.
- Mr. theymos goes with bitcoin but $100 weekly DCA.
You didn't mention timeframe, how long will they hold? What's the ultimate target? Without this info it's hard to tell who is wiser. At some point all three will dominate each other. We should assume that all of them are wise, because they bought Bitcoin. Alice likes to take more risks and put half of her money into altcoins. Bob and theymos are old Bitcoinheads, they know their investment will grow over time. In the end all of them will win.
