Now IEO, which are conducted by such exchanges as Binance, look more promising and more profitable. Also, almost all IDO, which are analogous to IEO, but are conducted by decentralized exchanges, from the very beginning of sales bring a profit of hundreds of percent in a few days. But the problem is that it is very difficult to buy such a coin at the price of IEO, since the number of people who want it is very large.
I think those decentralized ones are a lot better, we are not doing that bad with them neither, they are definitely doing better than expected, and that is what we are after here as well, doing not that bad and doing better than expected in these. Most look like scams to me, but when I look at them over course of few months they are doing great.
Defi investments on early days and waiting for a long time will result with a lot of profit. I personally did a bit of investments, I have invested into 4 defi projects so far and all 4 of them did returned me a great deal of profit, I really like it and I will continue to do it. I have managed to make 5x return from them total and as long as it continues like this I will continue to invest more and more, if I did another 5x in 3-4 more months I am going have a decent profit to actually start making enough for a retirement fund all via defi, not to mention my other investments.
