Why so many people talk about Idena?? Because of bounty thread in bitcointalk??
I guess they are talking about it coz the project is really good and indeed unique for me.
The op must have bought and invest on it that's why he's asking if it will be good in the long run.
For me, absolutely NO, how can coin with volume only around $100K can be the best altcoin?? So many top altcoins out there which Idena can't reach it.
Learn about crypto will give many answers
Cool thing happens in crypto, you won't really believe if it happens don't you? I'm not confident about this IDENA tho, haven't read about it a lot but the question is if it would be the best altcoin in 2021. If the price reaches a thousand of dollars next year then we can say that it is the best altcoin of that year, IF and only IF ethereum or LINK or XRP or TRON. My point with this is that , market is full of coins the investors are diversifying and we could not tell how things would really work in cryptocurrencies in the future in terms of prices.
