Well.. it depends on where u invest lol.. if u dont analyze coins before investing, u deserve to lose all the money. u can make some xs in the bullish trend, but be prepared to lose everything.. if company actually develops stuff it may be a good oidea but i think 98% of icos dont do anything, only telegram announcements..  rn bitcoin https://www.tradingview.com/symbols/BTCUSD is being manipulated cause of cme futures

well.. it looks like it went down because of the cme bitcoin futures.. price manipulation as always. https://www.tradingview.com/symbols/BTCUSD
i already think this idea with bitcoin futures or etfs is not the best, cause big money can push the price where they need

Esperamos que ayude a cambiar el sentimiento del mercado. Pero ultimamente incluso con noticias positivas criptos bajan. https://es.tradingview.com/symbols/GRINBTC/?exchange=BITTREX

Seguramente ya lo han hecho hace mucho.. Pero curiosamente estas noticias no afectan de ninguna manera al precio del Bitcoin https://es.tradingview.com/symbols/BTCUSD/?exchange=BITFINEX

Looking at the market I wouldn't try my luck investing in Altcoins. It's way more risky than casino..

That's called manipulation Even when news are positive, the market is going down. Why is that? There is only one reasonable explanation: fud to make people bet on holding and once the bullish trend is created, whales start shorting..  https://www.tradingview.com/symbols/BTCUSD/?exchange=BITFINEX

That's what happens when the market is bearish https://www.tradingview.com/ideas/bearmarket/. But some currencies are growing, like Ripple and EOS. Now, the reason for that is usability. If your product is in demand, then no doubts its price will grow. It's tru that there are many cool projects but still they lack applications..

Reasons for the ICO failure are very simple:

1) useless idea
2) useless team
3) government regulations
4) company doesn't follow its own roadmap
5) company doesn't meet its promises
6) token is not a utility but a security

Ripple is a basically centralized crypto and bitcoin decentralizded, yet. Otherwise banks would have never used ripple in their transactions. Still, precisely for this reason ripple is outperforming the market. Just look at this chart and u will understand everything https://www.tradingview.com/symbols/XRPBTC/?exchange=BINANCE

You are asking the wrong question.. How many altcoins are useful, that's how i would plaint this question. And the answer is - just few. The problem is that even these few are undervalued. For example, https://www.tradingview.com/symbols/GOBTC/?exchange=BINANCE Gochain's ROI is 0,54x in USD..
