the long way: Altcoin 
altcoins are very dangerous, the person runs a high risk of losing all money, I gave several times the example of siacoin, a lot of people kept saying "buy siacoin that will go to the moon", well many people bought when the price was 300 satoshi, 500 satoshi and 700 satoshi. see the current siacoin price: 0.00000063 BTC

a huge loss, glad that I heard a guy who posted a good comment on the Altcoin Discussion and at the time I sold my siacoins for the price of 300 satoshi
I want to invest some money. Is that right time for invest?
yes
where i need to invest this time?
invest in bitcoin
