It is not helpful to decide either bitcoin or altcoins or always try to swap those.
Most people just lose trying to do it at wrong times. Just hold bitcoin and good altcoins
will keep you ahead in long term.
They just read some twitter things and then they start making ETH/BTC trade and then they start losing their ETHs or BTCs. This shold be avoided. Without trading, people can earn money in holding their ETHs too. They should know this first.
