its always a good time to get into crypto in the long term. A mixed portfolio is always better then one investment, it may reduce returns but it decreases risk. For BTC I would wait for the fork and watch the trend after that.
Investment could differ from person to person. Priority needs to be that first is your country supporting it if yes then only invest. Because you may be investing for along term and say in between your country decides to ban it and you have to sell it might e value of btc would be down at that time so you end up making a loss. So ideally its a good investment for long run but based on various conditions for you it could be deiced if it was worth or not.
