Bitcoin is likened to the parent of Altcoin, so even though it's not all, when bitcoin rises, the altcoin average will also increase the price.
I will try to research deeper about Ethereum, Ripple, and Eos before choosing the option to invest.
Of course, compared to other coins, ethereum is more relevant for investment. But I advise everyone to look at the stellar, which showed quite good results despite the poor state of the 2018 market.
Of course, if you review the market for IPOs of companies and those projects that have successfully sold a token, then over the period of 2018, you can select several companies that should attract investors. This is not only pundix, but also the datablockchain.
