What is best according to you? Bitcoin or Altcoin?
It all depends on your goals. BTC is the market leader, although some altcoins, such as for example ETH, NEO contain more innovative technologies. It is difficult to compare. but you can invest and in bitkoyn, and in the altcoins, especially from the Top 50
It depends also to your money wether it is enough to invest in both parties but for now I rather to invest first in altcoin due to the prices are affordable .When we already a big amount of fund then it is good to invest in such potential coin like bitcoin.
