Hello,
Though i am new here , the knowledge i earned from my learning and personal experience its quite impossible for someone to make 1 btc without any investments. SO, if you got smart amount of capital it can be possible if you follow some logical ways and avoid playing/invest in gambling platform.
so my suggestions gonna be investing in :
- investing in trading platform (investing in crypto currencies - like Eth, LtC etc) and
- Bitcoin Mining
- Participating in ICO campaign as an investor

if u think my suggestions helped you then i will feel real good.
