I can't afford to buy bitcoin when there is a decline again later either at the end of this year or in early 2020, I only have a little capital and only enough to buy some other cheaper Altcoin, in some time I feel being played with by bitcoin prices this time
That's alright, buying altcoin can still give you profit at the right time, this market just move based on BTC movement and therefore we can expect that if the market will rise, its gonna be BTC that will lead it but like I said, the right time will come that altcoins will also rise.
personally, I also hold a lot of altcoins with almost worthless of value now, this is cause by the long bear market but I understand this is how it works because the pump created FOMO during the last bull run and the market was overvalued, so correction happened.
