It's funny, there are hundreds of coins, and a lot of them with high market caps, and some like Curecoin and Namecoin that seem to have reason to exist, but you rarely find people defending the reason for them in these kinds of threads. All the defense is in the announcement threads by the amount of energy keeping them going. The only reason an altcoin needs for existence is sincere people wanting it to succeed for some reason, like Dash, Doge, Ethereum, Monero, there doesn't need to be some cosmic written-in-stone absolute worth of its existence except if people want it there. Yes there are a lot of scams and naive teams but all the FUD in the world doesn't seem like it will slow all of them down. I understand the reason to focus on BTC alone, the rest seem unstable and a good way to lose money. But the creativity and sense of ownership for the small teams of people that are sincere shouldn't be looked down on, especially if it creates income and employment. If foolish people lose their money, they would probably lose it some other way anyway. No sense in blaming the idea of altcoins in general.
I can totally agree with your last sentence. i remember when back in Q1 2015 people started to blame altcoins in general, and since then even more crying babies appeard around here.
IMO if you are dumb or retarded you just easily can profit or benefit from a lot of altcoins.
1. First of all if you are a miner and you bought strong mining equipment, new coins are a MUST for you, since just imagine if 1-2 new coins would appear in a month. The cost of your mining equipment would never break-even.
2. If you are a trader you just need to catch the good entry and exit point and not blame the dev if you was dumb enough BUY HIGH, SELL LOW.
3. If you are a crypto-enthuasist is the heaven for you
