Most of these things don't matter if it is working well and the community is benefiting from it. But I prefer to stay with the new technology as it gives us more adoption with time and the world that it gives more users. BTC is something unique so I want to keep it off this list of being old technology-wise. The time of ICO has gone and there are other types of token offerings on the market so it will be better to use those instead of ICO. You will earn money in crypto if you follow the trend. Going against the trend can slow you down or cause financial loss.
