Yes, the great 2017 (and beginning of January 2018) party is over, nothing can be done about it without a time machine

After big party a strong hangover is nothing unusual. But after a recovery, new party will start. So be happy that you have an opportunity to join the next party, it is still only a beginning, still only a few people own cryptos and the total marketcap is relatively small. If you look back to the past, there were already several parties, much more will come, there is huge room for growth.
