i have about 40-50 altcoins in my portfolio. And the main condition is to hold in bitcoin about 40-50 % of their investment. It seems to much, but believe me that s really working strategy. When the BTC grows up at most cases Altcoins go down and there is the possibility to buy more cheap altcoins using BTC. When the BTC falls - altcoins fall much faster and again you have the chance to make profitable deal.
YEP! I agree 100%.
I admit that my goal for BTC is a bit lower (20%) and frankly I haven't been able to maintain it...the temptation to buy alts recently is too much for me to resist. It will be easier once I reached my goal $$$$$$.
As a testament to your wisdom, I've missed many good buying opportunities recently because I depleted my BTC holdings (as low as 2%
).
Ultimate plan is to be around; 60% long term HODL, 25% mid-term and 15% short term (flip/play coins).
