Buy bitcoin, that's the safest and most secured coin you can invest right now. Make it a habit also to read and research about the coins you want to invest in, of course people would want to ask opinion on others but at the end of the day it is still you who decides which coin to invest in, right?
I agree, with some additional. I think bitcoin is still the best coin to invest in, or at least, hold for the time being. Even if it had fallen in value for about 40% in the past few weeks, I would say that it is still in a good spot because it still holds a hefty 11.8k dollar value, which is still a good price point to invest in as it will catch traction and gain more value in the future. I also would like to point out investing in some altcoins short-term like with LTC, Ripple and Stellar; they are really promising with a lot of potential for increase in the next coming months.
