Many people like to say if... I will...

There aren't that many ifs...
If you go back to the past, you wouldn't buy BTC at 100 dollars, nor at 1 dollar... you would think it's a scam. Just that small-time scam...
Try more... be braver...
Although I often call out WLD, don't go all-in on WLD. My largest holdings are not WLD, but ETH.
The ideal portfolio is Uni + GT + ZEC + WLD. For those with lower risk tolerance, don't put all your eggs in one basket.
If in ten years WLD is worth 100 dollars, would you think 0.3 is expensive? If in twenty years it's 1000 dollars, would you think 10 dollars is expensive?
Expensive and cheap can be compared within a certain timeframe. True investing only cares about the direction, not the price... Price is determined by the market; if the direction is right, only time is needed.
