of course not. although now the price is fantastic. you can start from altcoin, then trading and if it can be changed to bitcoin. the oldest trying and the spirit. the price can still chance to continue to rise.
You are very much right. I think it is never too late to invest in Bitcoin. In fact, this is the right time to invest your money and buy Bitcoins as much as you can. It is because right now, the market price of Bitcoin is going down.
So you need to decide and decide wisely right now as you wont be getting this opportunity in coming days.
