This is the best time to spend profits in 2017 and early 2018. We still have at least 2 years to go before reaching ATH again. Accumulate now and enjoy later. In every trading, there will always be a market downtrend, though not always followed up by an uptrend, it could be a possibility.
The chance that we will never see a big price increase is also not small, so if you invest, then only the amount that will not be sorry to lose, take out loans, as people did before, is clearly not worth it
