"better" is a hard one to define. I asked AI to work out ROI if a person did $50/week auto investment into bitcoin from 2017 to now. I bought my first full bitcoin thanksgiving of 2017 and sold it in Dec for double. since then I've only had a little btc here and there. I always wish I had grabbed $3k btc during crypto winter, but I instead have spent the years DCA'ing into XRP and FLR.
I have held along the way LTC, SOL, XDC and many others. I used to DCA like $50/week into Litecoin all year, and then sell at a profit every winter to pay for a vacation or help subsidize it.
Now whether BTC is a best investment option just depends I think, on whether or not you believe it's a real thing that will continue to appreciate, a scam, immoral, or something else. If someone gave me $2 million cash today, I'd probably spend it on real estate somewhere like AZ and use the rental income to retire my wife or myself if possible. but even housing is expected to have a pull-back in values soon and counting on rentals to always be full without a house getting a leak or something is another stressor.
