I personally have bought quite few, usually the Ethereum based ones mostly do good. Had some disappointments though. Wasn't very successful with the wave based ones ...
What about you ?
Ever since the crash began, I managed to buy a few coins which I assumed that they are solid enough to make me profit when all cryptocurrencies begin to recover in the coming days. I bought some monero, litecoin, ethereum classic, waves, ark, omisego, komodo. I considered this crash as an opportunity to invest more into these cryptocurrencies. From now onwards I will be holding for a few months, I am waiting for the value to go up again and then sell. I will be buying some more monero later this week, before it goes above the $100 mark.
