There are tons of different opinions. You may want to look what /biz/ currently says!

One approach

 * 1) Make Kraken/Coinbase or Gemini account
 * 2) Transfer FIAT (your money in $ or EURO)
 * 3) Buy ETH
 * 4) Hold it
 * 5) Study coinmarketcap.com and look for interesting coins
 * 6) Research these coins, check if they are worthy of your money
 * 7) If you want to buy some altcoin; trade your ETH for BTC
 * 8) Make Bittrex account and send your BTC there
 * 9) Buy altcoins when they are in "red" low price
 * 10) Sell when they are in "green" high price or hold, if you think they are going to rise higher
 * 11) Don't fall for meme coins, if you fall sell them after some small gains and then buy the dip
 * 12) Research stuff at bitcointalk.org it's the birthplace for many successful coins.
