People was calling BTC a bubble @ 15, was calling it a bubble at 20, was calling it a bubble at 30... then it blasted. It didn't made those people wrong.
Gold is in the same path, sooner or later will blast, for those lucky enough to jump on its peak will be good, for those entering or holding there will be a nightmare.
It's pretty pointless for me to talk about this with you, because I can clearly see you don't see things the way they are.
Super short explanation.. BTC at 15 was overbought and it was bubble in the making. Gold is trending right on its technicals, which you can see on the chart I linked. Gold is hyped by millions upon millions as a protection against inflation. Its easy to buy/sell and free to store. It doesn't take much space to store 1 mill worth of gold. Big boys play a big role about its future price, they will ultimately decide when enough is enough.
Of course gold price will eventually top and then selloff and people like you will laugh and write pages that you knew this all along. But if someone who invests in gold has an average price of $1000 and price tops at $2500 then crashes and drops to $1900, where this poor soul finally sells his position, he/she still made 90% profit. Making profit is the name of the game. Every monkey can predict that everything that ever went up will eventually top and then go lower. Timing is everything and timing is what you missing.
