with 2 btc I would buy some platform tokens as Bancor, waves, ethereum, ardor, stratis. Then i would buy some "exchange" shares -tokens as binance coin, kucoin shares and coming dtr - dynamic trading rights. I would finish my shopping list with some longterm picks as TAAS ( dividend paying token ) and Iconomi tokens ( buyback/burn ). Also spare some eth for upcoming ICOs like blocksquare and diw.
