Many people think that they should invest in BTC, and I choose both. ETH is being developed very well by their team so there is no need to be shy about investing and it.
Everyone should have both bitcoin and ethereum before other alt coins, these are two most popular and known cryptos. Very active development and always upgrading, but I will choose bitcoin, I am here because of bitcoin. Trying to sell bounties to get more bitcoins. It is future.
Of course, a very correct strategy when a person is engaged in accumulating Bitcoin by any means, but at the same time has other sources of income for life. In any case, Bitcoin will bring huge profits in the future.
