It had a dump when most people received their tokens from ICO. It fell well below the price many had paid.
I bought a little in that mega fall. But I sold it when it went up. I think the problems will start to emerge now and will have a new fall. Especially if more exchanges open trading at that time. The volume is very small, there are few exchenges and almost nobody sent them what they won at ICO.
But in the long run it seems to me a reasonable bet project.
I agree with you that Tezos can be doing very good in the future so for those investing in several altcoins it's worth considering at least. But why are you saying that about current trading volume and exchanges? 2,492,398 USD in 24 hrs isn't a small volume. XTZ is listed on HitBTC, Bitfinex, Coinone and Gate.Io. Those are are not insignificant exchanges. The smallest of them, Coinone has 17 million USD daily trading volume. Tezos now costs almost less then ever and this can mean two things, either the coin is dying or it will rise a lot in the future comparing to today's price and thus worth investing. I wouldn't go so far to call Tezos a dying coin.
