As a newbie, I want to know the features of a good coin for which its value raise in market. I think its purchasing capability is mainly responsible. What is your logic?
In General look at the btc value rather than usd value. Look at marketcap rather than the price of the coin (4 dollar ripple is not cheap).
As for the actual product firstly see that they actualy have a working blockchain (verge anyone).
Look at how large the community around it is.
Look at who controls the mining, whether it is a pre-mined coin, Who controls how much of it (again to say ripple is decentralized when the company control 60% of all ripple is just blasphemy).
See whether the team has delivered on their promises and deadlines. Or whether they just make announcements to pump and dump the prices.
Dont just beleive nonsensical claims made by team or the whole tokenize the world bullshit. The fact is that a lot of industries and sectors dont need to be decentralized and and that centralization does have its many benefits.
I as a rule stay away from coins that say xyz industry is worth trillions/billions of dollars and if we manage to even capture 1-5% of the market my coin will be worth this many dollars. I also as rule stay away from coins related to music/ entertainment/ adult industry(vice and such and such)/ farming and other bullshit fields.
Remember that while there is a lot of scope for growth, crypto currencies are primarily being used for speculation today. So when ico make these sort of bold claims its generally better to stay away/stick to bitcoin. You will get more opportunities.
Anonymity coins(monero/z cash) by the way are hugely undervalued and are always a good bet/will always have massive usecase.( offshore banking/hawala/quietly moving large amounts of money) May be unethical but its been part of the world for thousands of years. Best not to be naive about it.
