Tezos is interesting because it is at the top rank to 15 for now, I think it does not hurt to invest to them for the future because the top altcoin definitely gives maximum profit if there are no constraints like the developer escapes The project. So my prediction now some altcoin go up following BTC and hopefully also this Tezos follow them in order to be competitive with other Coinmarketcap Top Rank.
They have a interview about Tezos. Great news for 2020!
