The Bitcoins have a lot of forks and you decide on investing and holding is a right decision. But investment in BTC is a long-term investment because the exchange rate of BTC is not as sharp as altcoins. So if you decide to invest and hold at least 2 years, BTC is a good choice in the current unsettled exchange rate.
Holding bitcoin fork coin is a bad decision so far, you must see that how the majority of bitcoin fork price has been getting a lot of dump and look at these fork coins and they have been loosing a lot of value.
It has no usefulness to hold your bitcoin for coin today.
