Dead party? Holding and trading doesnt give out profit? Here is how to earn some btc on the long run, buy one btc now and hold it, in the next year, when the price goes almost double you sell it = profit. Also, getting a job wouldnt be too bad... Signature campaign, writing articles, programming, web design... You can earn btc only if you want to.
Most likely that poster meant to say that it is no longer possible to make quick bucks and earn thousand percentages of profits in Bitcoin, like it was when one day it cost less that 1 dollar per BTC and then, in a matter of months, it suddenly cost $50 per BTC. Or when it was possible to mine a few thousand bitcoins on your personal computer and now become a dollar millionaire. Those times are long gone, indeed, and you need something more than pure luck, Internet and a desktop computer...
Something more than just turn up in the right place at the right time
Theres one thing that bitcoin holders can do which is endless. Trading is what mostly are doing, you can either invest to an altcoin/token or just buying and selling bitcoin as price fluctuates.
