the unstable market conditions up and down  And waiting for altcoins that I have to do development until it reaches a high price, so it can give me the advantage of investing in it.
 although I can trade and make a profit. but I don't do that. because I'm too tired with my daily activities. I consider it a longterm investment. so as not to be affected by daily prices. although today the price is down, I can still relax.
