One word Diversification
All the options said above are great and you should invest in all of them little little. If one if them fly away or occur loss you can recover from other.
If you are new to trading and trust me i can trade on behalf of you. Generally i make 4% profit per month.
I believe this is good advice. Remember to put your BTC in cold storage with only 10-15% for good use
In my opinion, holding your coins is more then investing your coins at this moment as the bitcoin halving is in its way..
any time its price can hit $600+ or even more

and profit is for sure !!
