This is very true. We may not get any next btc but we can get altcoins which can grow tremendously and give investors enough profit. To me what matters most is making profit out of my investment and once any coin can do so for me, that is my next btc
Indeed, there will be restrictions with bitcoin, but frankly I still really hope that bitcoin will continue to be loved and hunted, until now there is no big breakthrough from altcoin and still not and it is still very difficult for altcoin to replace bitcoin. starts when will there be a strong altcoin that can replace bitcoin? ethereum, until now, still depends on the growth of bitcoin.
