Now implementing this strategy is the most ok, because the current BTC prices are very low and can fall deep, so buy them now do not miss the opportunity.
buying btc is good but selling alts this time is not that good because the price is also low you can sell it but with a low value so it is better to hold it and buy bitcoin form your fiat but if you got nothing you can sell your alts because the chance you can earn with a good value is on the side of bitcoin.
Yeah at a time like this, it's not really a good idea. Unless bitcoin starts to make another december 2017 run then i'd gladly sell most of my alts even at a loss. But ifnit's like this, there's a chance you'll even get more from your alt holdings than btc
Yeah, both are currently running in their low market rates at this stage so the relevant decision is to buy one other these two or you can invest in both for your better future outcome. Let us suppose that if the value of Altcoin is on its increase trend then better you invest in Altcoin that will enable you to get fine profit after that you can use that profit for your Bitcoins investment too.
