All of my close circle friends consider crypto as scams, and I cannot convince them at all. They all bought some meme coins and lost, or have heard stories of people getting wrecked on NFT coins, so they blame Bitcoin for all the scams
Most of us here had rugged past with crypto dealings, you don't need to convince them, you can point them to Bitcoin price history to see for themselves and ask them to do their own research. It's very wrong to blame Bitcoin since they didn't buy any instead they were fucking around with pump and dump shitcoins and it's associates.
When I argue, "Why don't you buy Bitcoin?" they say it's not profitable. When I counter back with, "If you had bought $6k BTC last year, it would now be around $10k instead you chose some meme coin that online gurus talk about, and now you blame Bitcoin," they still don’t listen. Nowadays, I’ve started to lose friends over these arguments, and I'm not good online Instagram or Discord either.
In this case you don't need to argue, it's pointless. Give them the price history and ask them to monitor the performance in this bull run. I have been arguing with my sister from last year to buy Bitcoin, but she holds past aggression from her shitcoins involvement. I simply asked her at the beginning of the year to observe Bitcoin during this bull run and see what she's missing. I just got off the call with her two days ago with her telling me that she must buy at least $50k next year.
Most times arguing is pointless, direct them to the right information source and they would do the convincing themselves.
