I feel ya. I've been hesitant to pull from my XRP because I bought them so low. I'm just mad that I couldnt put more money into it earlier so I could do what youre doing.I put $1500 into XRP early on then felt I was getting carried away so I stopped...but when that shit blew up and went down a bit I spent about $1750 on a shitload of other coins...I had about 11 other coins but ultimately that $$$ (keeping in mind I did profit a decent bit off most of these coins) plus about $4500 I skimmed from the XRP profits went into bulking up holds I had on verge digibyte strat and siacoin...w/ XVG and DGB I got lucky and went in before they hit their new run...I could be way up on these other coins (double on everything) if I hadn't been so stubborn about only holding on to XRP...I've been getting a heck of an education tho these last few months...crazy shit is I still don't really know the tech aspect of things
I have about 15K being held hostage in Polo and thats what I would be using to apply your method but Polo support are hos.

The problem for me at the beginning of all this was buying bitcoin without jumping through so many hoops.
Now that I'm Tier 3 and 4 everywhere with my accounts linked up, putting money in is easy.
It just took weeks to get situated like that because these exchanges and bitcoin sites are so slow with responding.
