I've been in the crypto world for over a year) and worked out for myself 3 ways to increase the deposit:
1 is trading (in a growing market it is very easy to earn profits)
2 is participation in ICO (good projects from time to time bring profit)
3 This is Bounty (year round brings a small but stable profit)
I agree with your way to profit. Also I decided buy BTC now - good price for me. Another approach for take a profit - it is wait) It is difficult for me, but I hold some coins more 6 months.
