Bitcoin is one of the most successful long-term investments in the market. How much to invest depends on your financial condition and your source of income. Make sure that the investment funds do not affect your quality of life and needs. Better to invest in bitcoin first and prepare a reserve fund to upgrade volume, as the market fits into the next investment. Now, this time is perfect for making upgrades and expanding the number of bitcoins.
I welcome the perception in your investment. But if the ICO is better than the speculation bitcoin. And the profit generated by ICO is better than bitcoin, that's a false view. When you invest in some ico and they run away with your capital. You will think again about the consequences.
