I didn't live through that golden age you wrote about, so I'll have to take your word for it). I started playing on PokerStars in 2009, when it was already hard to win anything in online poker. Of course, people are getting smarter every year, many have turned online poker into their main source of income, they play like robots for days on end and constantly hone their skills to the smallest detail. That's why it's getting harder to win money every year. But harder doesn't mean it's unrealistic, I'm sure that even today you can be a winning player and make good money playing online poker, we're talking about those people who have dedicated many years of their lives to this business and who understand this game, and not just play it. Here, in principle, as in any other field of activity, people are constantly progressing, so I think that it will only get harder every year, and unfortunately, that golden age you're talking about is unlikely to return). Good luck at the tables.
