Buy alt coins is the best way to accumulate more btc in my opinion
Buy bitcoin and altcoins in the red zone, the best time to buy altcoin when price drops. Yes btc is the best investment as the price will continue to rise. So, both are profitable for me which really offer a profit.
I think for me i will prefer altcoin over bitcoin at that time to gain more and more profit from it. I think the margin of profit on altcoin as compare to bitcoin is way better than that of bitcoin. bitcoin will only recover its price but through altcoin the margin of profit is better because they got much low at that time and when they retain their price to previous you will be good enough to make more profit through it.
I am not against buying altcoins but buying them at the cost of bitcoin just because its price is decreasing or something like that would not be much of a smart move. Those who have been in the digital market for even this year would understand my point very well.
Bitcoin has a large recovery power. Since the last dip, it has just skyrocketed in its value. Holding on it for long can really make the holder rich. I cannot force anyone but I have been sincere, do not sacrifice bitcoin for altcoins.
