Bitcoin rally today is huge and it must end at some point.
Now I want to swap part of bitcoins into alts with only one goal - to gain bitcoin value. What do you think? What alts will raise in bitcoin price in next days if bitcoin begin to fall in dollar value?
You are partly right you can do it, but do not exchange all of your Bitcoins for altcoins. Leave in your wallet your BTC and do not touch the currency. Buy ETH, Cardano, NEO and some minor alts to trade and make profit.
