The world is moving very quickly, and countless unpredictable factors affect us in more ways than we can imagine. Employment, climate change, and everything else that can happen is on its way to happening, but we can't take advantage of it, can we? If we can, then we should.
This is obviously not investment advice, just my opinion, but I believe that it is in the field of cryptocurrencies where we can take advantage if we are attentive, not only because we understand them, but because it is where opportunities for profit arise on a daily basis. As for the price of cryptocurrencies, don't feel bad, something similar happened to me, because I had several units of ETH years ago when it was worth only $400 (or a little more), and I sold them all during a small rise in the price at that time, because I didn't have liquidity.
I think and know that what always affects those of us who don't have much money is the issue of liquidity, and if it weren't for that factor, it would be easier for us to make money. Even so, I plan to keep trying and won't lose hope. As traders and investors, we know that windows of opportunity are always open to the attentive and discerning eye.
