I would not say it is wrong but like what all the veteran traders always say, diversify your portfolio. We never know when will btc have its correction because when that happens, those who hold btc will surely exchange it and spread it into different altcoins. There is always a sure pump in altcoins after btc and I'm very excited to see my portfolio go to 10x.
All the investors are continuously investing the Bitcoin and it will reflect in the current market. In case we can exchange our Bitcoin to altcoin it will reflect to you only, because market stability is important to maintain the holding our investment. If we have Fiat currency surely we will invest all the money to Altcoin or Bitcoin but exchanging the direct trading is not a good deal.
