i am using BTC from almost 2 years and now i want to invest in other cryptocurrencies i just want to know is it profitable to invest in ETH and LTC because these are the fastest growing currencies after BTC,just need your suggestion about it.
for the long term: yes. for the short term: no. I think if you want to invest in ethereum, then the long term will be more effective. but it all goes back to your own analysis and point of view.
If you have BTC hold on to it as there is more momentum in it compared to ETH and LTC recently.
Beware that this is not being better or worse. The story is far behind this, it's all about the market expansion and traders. For eth, there are Korean investors for it. For ltc, there are chinese investors for it. Evaluate like this.
