In my own opinion ethereum is definitely a good one.. But I think there are a lot of good projects still in the pipeline.. My best pick from the ongoing ICOs at the moment is The ABLE project... Crypto-Finance is an interesting topic to me
Good advice but in my opinion I think the dominance of the bitcoin is just a psychological thing.. There are other blockchain with way more functionality and profitability compared to bitcoin. For me am a huge fan of ethereum..
