Thank you for your answer.
Can you tell me where can I find low cap coins ? Where buy this coins ?
And do you have a Portfolio of low caps ?
Thank you.
Low cap as in low market cap.

Anything below 1 million has great potential.

Always research the project, don't go throwing your money around at everything you find.

When you buy coins for hold, did you store the coins on Bittrex or Poloniex ? Or on a private Wallet ?
I wondering that because if I buy 10 differents coins I need to download the 10 wallets ?
There are some hardware wallets that store more then one coin. So put 4 coins there. 3 coins leave on Poloniex and 3 leave on Bittrex.
