I think it is base on his or her choice of earning BTC and ETH. Main while, there are several ways to earn BTC and ETH.
1. Been in this Forum ( altcointalks) is a brilliant way to free token. All you just need is just to be very active on the forum and contribute meaningfully to the forum discussion with constructive posts.
2. One of the easiest ways to earn Bitcoin or Etheruem is to invest on these projects by buing these coin/token on various exchanges out there.
3.Also, one good option on how to earn BTC and ETH is through trading. As most of the large exchanges allow cryptocurrencies to be traded for one another, crypto traders try to make money just as foreign exchange traders do – by buying currencies when they feel they are priced low and selling when they feel they are high.
4. Another good methods of earning of earn BTC and ETH is through peer-to-peer cryptocurrency lending. Platforms such as BTCPop and Bitbond match lenders with borrowers who are willing to make repayments with interest. As with peer-to-peer trading, reputation and feedback systems help lenders make educated assessments of the risk of each particular loan, and borrowers can generally “earn” the opportunity to take out future loans at lower interest rates by showing that they will make repayments on time.etc.
