If I were to give a recommendation, actually, I would say that ICOs are not a good way to recover your investment.

The most straightforward way to recover your losses is to sell it and then reinvest.
Cut your losses and then use what is left to reinvest into one of the major coins that perform well (btc basically).

If you have lost so much that it's not even worth selling it, you can either wait or buy back in.
If you have hopes it will go up someday, you can buy more of the coin.
That will vastly decrease your cost per token which means when you eventually do sell it off, it will be easier.

Of course, you could just put aside a percentage of your income to regularly invest more into a stable crypto.
Bascially, if you lost money because you made risky decisions, than stop making risky investments and go with stable ones.
