I believe the future of Bitcoin will be the best coin. I'm not sure if there are other coins that can replace Bitcoin. Bitcoin will still be the first coin in crypto and be the coin most wanted by everyone. I am sure in the future Bitcoin price will be fantastic, therefore we should buy and invest in Bitcoin right now!
Everyone is thinking about the future but they do not have to be much serious about the future because we should think before investing here as we know that this is favorable for long term investment and if we know about it then do not think about the future. Just check the value and get updated with the market, when the value goes high then sell your coins on high price to get profit.
