It's completely outrageous to be having such an allocations in my Altcoin portfolio.

Of course, it is.

I'm still down 65% on the entire portfolio.

However, I'm willing to do this as I know that the upside stretches more than 200%, 500% or 1000%.

In order to achieve that result, you'll need to be able to accept the fact that you're going to be down a ton too.

If you're not able to go through that phase, then you should adjust your portfolio entirely.
