Ouch you missed an opportunity to buy bitcoin and altcoin last 2017.. oh well just wait for another epic bull run in next coming years and hold your crypto especially bitcoin since the halving is coming in 2020 so just keep holding and let's see if the hype for halving is worth the wait.
Everyone is waiting until 2020 to return because this is a year that is expected to be an economic development year so the crypto market will receive a lot of special attention from investors. I think the year of holding Bitcoin is the only option that will help you to make money during this time but also need to be more careful because the bear market is still likely to happen at any time.
