Bitcoin and some basic coins are good to have as a safety option - there is a suspicion that the situation will change greatly and bitcoin will cost many times more.

And for the future, you need to look for good ico projects-to look at what to eat and choose a few-there is always a good potential for growth.
I'm currently working with such a company.

You can see that the market is constantly changing and bitcoin prices are dropping sharply, which will cause the price of altcoin to fall, so I think you do not have long term investment at this time and you only Day trading and short-term investment should be avoided because bitcoin prices may continue to fall sharply at any time.
