I don't understand what you mean by there is still enough time to invest and also waiting for long before investing.
I don't think there is any need waiting for long time before investing into Bitcoin if the money is readily available and also having some basic knowledge about Bitcoin investment and also ensure the security of the wallet where your Bitcoin is kept to avoid been hack by hack by fruadsters, trying to wait for long time before investing might lead to procastination so it will be better to start now and adopt the DCA strategy of accumulating Bitcoin where you purchase regularly either weekly or monthly irrespective of the price of Bitcoin and HODL for long.
