1. How do I know that this Altcoin is a good altcoin to invest in? (Not another Pump and Dump)
all of the existing altcoin are pump and dump so this question is moot.
2. How to analyze an Altcoin Fundamentally Speaking?
this is such a broad question, i am afraid the only answer that i can give to you is to advise you to learn fundamental analysis! but that may not be the best thing you can do with altcoin investment.
3. What are the indicators that it is an Altcoin for growth?
hype!
if there is enough news and big exaggerations out there about that altcoin, that means that atlcoin will rise up (get pumped) and you can invest in it. there are technical analysis you can also do on the charts but this is altcoin trading we are talking about not a real legit market with little to no manipulation!
I think Hype can be translated to Demand. But the real question is why is other Altcoins have bigger or greater demand compared to another one? There is always a reason why is it having a better value aside from the hype. I mean you can hype it up all day but only a few will succeed in terms of its price.
Without comparing certain coins it's hard to say.
ETH is strong because it has a strong community behind it. If you're going to dump your coins there is always someone there that's willing to pick it up. If you play the market you already understand how this works. It has a strong community behind it because it has constant development and updates. Because the people behind it are fully-focused on it and hold many different meetups and whatnot. Because the codebase is unique and what they're offering is/was too. I don't have any ETH, but I wish I bought it in the crowdfund at $1 per coin. I don't think I was even registered on the forum yet, though.
How about DASH? Or Monero? Well. All I can say is that a lot of the coins that came out in 2014 are starting to see a rise now, maybe that's the sweet-spot we can look for in the future. 2 - 3 years of active development and a coin will start to show it's true value? Maybe. I stopped mining DASH when it was still DRK because it seemed like a waste of time. Wish I never stopped. I didn't buy Monero because it was already $1 at the time and I wasn't looking into it enough, more regret. Monero again was a unique coin. So was ZEC. I don't know about DASH. The most common thing I find among coins that break that $20 barrier is they have something especially unique about their code.
Altcoins that have less demand have different reasons based on the coin. How long it has been around, who is behind it, what they offered the market, if they stuck around, total supply of the coin, mining rewards, pos rewards, premine, etc. The reasons are endless. That said, most people will diversify as much as they can and hope for a winner. Winners will pay for the losers, ideally. As I'm sure you already have learned from the stock market.
Making 100% is quite easy in crypto, but much harder in the stock market. Even a 1 satoshi coin can be profitable. If I had the money I would be investing in almost every ICO, even if it looked like a scam. Why? Because you really can't know what will happen in the future. A coin that starts out as a scam might end up with a different developer and worth 100x what you paid for it.
