Hello @crypto.piotr
Interesting topic you have brought up for discussion. For some it might be daunting but for others it doesn't come as a surprise. In the end, we know that the price game in cryptocurrencies is often very risky.
About 10 days ago I was reviewing the price history of BTC and also of some altcoin, and I think that BTC has not yet exceeded its maximum price, however, if I think it will exceed it this year, of course, I may be wrong, and then a tremendous correction could come from which we must guard against.
Get the benefit and retire.
Coincidentally, some 14 days after BTC reached its maximum price, some altcoin, including steem, reached their highest price in history. History repeats itself, considering the cyclical nature of the markets, we could obtain good profits, but everything is yet to be defined, nothing is written, at least not for the future.
