This may be bad news to many of you, but I plan on shutting down Delta Investments (again) within the next 1-2 months.
Certainly is a bad news, I was planning to up my investment in you/your skills next week

I see this service as superior in terms of ease of use/returns to anything I've seen in crypto for very long time.
... and involves no headache of constantly depositing BTC ...
Agreed, this is a headache and frankly I respect how you do it every single week with alts trading conditions changing by the minute. But if this is a problem, how about changing the terms of investment in D.I. - I mean to manage it like a pro fiat fund:
1) Deposits will be used for alts trading&mining
2) Deposits (principal) wont be returned every week (or two/three) but will be invested and traded with (*)
3) Interest/returns would be paid weekly to designated btc addresses - and you would pay it in one day you choose as a payment day for all investors that suites you best or that is best according to alts markets conditions and your opened positions.
(*) Once investor wants to withdraw initial deposit (liquidate his share in the fund) he will issue a week or 2, 3 weeks notice to you (fund manager) and once that period is over he will receive his initial deposit allowing you to plan ahead and gracefully liquidate some of your alts positions as to not screw potencial profits for you and other investors.
I believe this should minimize most of the hassle with management of D.I. The only question is - if you and/or other investors here would agree to these terms/or similar ones.
Anyway, best of luck trading Adam!
*edit - or do interest/returns payment biweekly = same as you'll be paying to OMC holders...
