what i suggest is to still hodl, and if you have a lot of extra cash,try buying, however it's up to you to take the risk. we all know that bitcoin gold is only a few days away, however, the price of bitcoin is becoming very volatile as of the moment, it goes 300 usd up and down by 200 usd and vice-versa, before having the bitcoin gold, i see that the best way is to hodl bitcoin and buy altcoins, since the majority of altcoins now are now taking a dip, and soon bitcoin gold will join them too, since right after having bitcoin gold, majority then, will use their bitcoins to buy altcoins since they are still low, and then we will certainly see a drop on the value of bitcoin and a rise to altcoins, then after that, the correction will take place and you can buy bitcoins at a lower value, compared today. i  think for bitcoin, the strategy is still hodl for a long time, and buy altcoins for now, wait for the correction, then buy bitcoins afterwards, the key here is still delayed gratification, we should just let bitcoin go higher and higher and after several years, we can spend a bit of bitcoins we have invested on.
