We couldn't confirm about the btc bottom rather than we can expect that btc no more further downward movement. As you can see when btc Down alts coins become too much down as well as btc. Both btc and eth are strong fundamental coins and even I cannot suggest you to invest all money in this . Now I feels like btc no more huge further hard dump . That is very worse condition if do possible. Now alts will definitely pump when btc up
Yeah, it's a good sign since BTC is not moving any downward rather than we go up at a slow pace. But we can expect to have a big move this year since many things that affect to crypto market, also we can keep buying the dip so we do not miss any opportunity that we can get. Don't forget to avoid any FOMO out there to prevent any losses that you didn't want.
