Is your question on the right forum?
If it is somehow connected to this sub-forum, then when you say investing, do you mean mining?
If it is so, then probably it is worth "investing", understood - mining, one of the big altcoins - Ethereum, ZCash, Monero.
I am thinking about making a rig with 5 or 6 GPUs to mine Zcash.
Will see what will happen.
Too hard to find the GPUs.
But this is understandable.
