unless you are able to invest in a computing system that can competitively mine coin for you, the best way to enter at the moment is to invest your country currency (ie USD) in a mine and let a miner mine coin for you. one very trusted miner is based in Iceland. Genesis-mining.com. You're welcome to use my code VC4XLA for a discount when opening account. You may also buy from an exchange such as Coinbase or Xapo but cheaper to buy directly from a miner. This is my basic understanding. I seek correction where I'm wrong. Happy coining.
