But I don't know why Bitcoin is still up and ETH always maintains current prices.
Why did that happen? And now, I have to invest in Bitcoin or Ethereum?
thank you
Invest on ICO, in that case, you just not invest on bitcoin at the same time, invested on another altcoin on the behalf of your investment. You earn and helped the crypto community.
Investing in an ICO project will be profitable if you correctly identify the advantages of the project and have collateral from fraud. BTC and ETH very clearly provide more opportunities in investment, all you need is intelligence in taking the opportunity to get profits.
