In markets there are two people, the first who are experienced in the market and see these correction as opportunity to increase position, and the ones who are new and panic sell and think every think will crash forever. Take a minute and figure out which group you belong to, take your time to learn about the technology behind BTC and what problem it solves before judging its future.
It's hard to tell what's the bottom of this market. In general, it depends on your goals and if you're trading or holding. Now we are in a correction, this is usually a good opportunity to increase position or re-enter coins you believe will do well in the future.
I think it's basic when you get into trading/investing that high risk = high reward.
Obviously if you fall into the conservative approach of investing, holding BTC or ETH would be the best options especially in a bear market. However, altcoins always do better in the bull run, so my advice wait and HODL.
It differs from a person to another and what kind of bounties you participate in. I'd recommend you to visit the previous old bounties and take a look at the final spreadsheet, this would give you a hint on the rewards.
